Do you have experience working with different CASE tools? If so, what do you have experience with?

"In my current role, I regularly utilize both diagramming and web development tools. The diagram tools assist our software projects by outlining the system data and components in a graphical form for us and this saves us a great amount of time while also being very reliable. The web development tools greatly help me visualize site changes that I am making because I don't have a deep background in web development. If hired for this position, I'd look forward to learning other CASE tools for prototyping, quality assurance and maintenance."

The world of software engineering has greatly benefited from advancements in computer aided software engineering tools. Because Mendix is at the forefront of the industry, your interviewer will be looking to hear which tools you have experience with. Make sure not to concern yourself with providing a correct answer here, but rather focus on your flexibility to learn new aides when needed while explaining what you have experience with.

"During my career and in my experience with CASE tools, most of my experience is in the lower CASE elements that focus on coding and testing the software after initial development. CASE tools have certainly made life as a software engineer more efficient and effective and I'd look forward to learn any new CASE tools if hired for this position here at Mendix."

Do you have experience writing a custom exception in Java?

"Yes, I certainly do have experience writing custom exceptions in Java in my time in the financial software industry. Because some of the business logic and workflow needed customization, I was tasked with extending the exception class and all subclasses in standard Java to create the custom exceptions needed."

As a Java expert, you will hopefully have the ability to inform your interviewer that you do have experience in writing custom exceptions in Java. As a reputable software company, the engineers and architects with Mendix often need to demonstrate the ability to do just this. While talking about the experience that you do have, be sure to discuss your thought process in initially determining the need for writing a custom exception above and beyond the standard Java exceptions.

In SQL, how do you explain the differences between clustered and non-clustered indexes? Can you name a time that you used each?

"In the simplest of terms, a clustered index order records in a table the way that they are physically stored. There can only be one clustered index per table. Non-clustered indexes do not store data to match the physical order that it is stored. Rather, it can hold up to 249 indexes per table. Both types come with their own benefits over the other. In my experience, clustered indexes are suited best for programs that use primary key as an identity integer column. On the other hand, non-clustered make the most sense for programs that need JOIN and WHERE clauses within them."

Mendix uses indexes to improve query performances within their software and for this question, your interviewer is looking to hear that you have a basic understanding of both clustered and non-clustered indexes. Explain the differences between the two types of indexes and be sure you can either speak to relevant times that you've used each or when would be the appropriate application to use each.

"In my experience, clustered indexes are faster to read but very slow when it comes to update data within. Non-clustered indexes are just the opposite in that they are slower to read but much fast to insert new data into them. In my current role, I mostly use clustered indexes when large numbers of rows need to be retreived and when insert operations are important. Most other times, I will use non-clustered as the standard."

Do you have any unique skills or past work experiences that we can't see on your resume that would benefit the team here at Mendix?

"In my current role as a data engineer, I have gotten the opportunity over the last five years to work with clients in many industries. One of the industries that I've worked most closely with has been the private insurance industry. This experience and my gaining of insider knowledge in the insurance industry would benefit me greatly if brought aboard the team here at Mendix."

This question is providing you the opportunity to potentially set yourself apart from your competition for this position. To do just that, it will be important for you to make sure that the unique skill or experience that you discuss matches with a critical need for Mendix and the position that you are interviewing for. Whether you talk about a unique skill or experience, your research on this job will prove vital in your ability to make sure that it impresses your interviewer.

If you were confronted with a time where you wouldn't be able to meet a deadline here at Mendix, what steps would you take when you made that realization?

"In my current position, I am very used to handling multiple tasks and projects on a day to day basis. Last year, my team was tasked with what started as a low priority project. After assembling a team to initially discuss the details and set a deadline for completion with our management, the project unfortunately fell off the radar of everyone on the team with many more high priority projects coming up each week. As the initial project's deadline was within a week of being due, our CEO reached out to me for a progress report. I immediately took full responsibility for letting this fall off the radar and I ensured our CEO that we would have an updated timeline set by the end of the week. In doing this and completing the project to his satisfaction, this was really the tipping point in our department moving forward utilizing a detailed project management tracking system. To this day, I can't say enough about how appreciative I am about utilizing this awesome system. Moving forward, you can rest assured knowing that I take full accountability for my actions and do what is necessary to communicate new expectations and meet them fully."

At some point in any person's career, the inevitable happens and an important deadline needs to be missed. With your interviewer fully understanding this fact, they are solely interested in how you react to this situation and what you do to make the situation right. In your answer, focus on the refocused planning and communication needed while also avoiding blaming others for the situation. Your interviewer holds accountability as a desirable virtue, so be sure to take accountability for actions in your response.

"Having been in this situation before, I would first sit down to gather all the facts possible in the situation. What was the deadline, why wasn't it met and what can be done are all important questions moving forward. From there, communicating to all key parties is extremely important and doing so in a timely manner is critical. In this communication, taking accountability and setting new expectations for delivery in a concise and tactful manner will most often put stakeholders at ease and allow for successful completion."

What skills do you use to cope with the day to day stress and pressure on the job?

"Where many others get overtaken by stress to the point that they can't function in this field, high pressure situations sharpen my focus and that helps me work through them with ease. Last year, I was assigned a high priority, short notice project for a high profile customer. My manager gave it to me because of my proven success in those situations. From the start, I created a timeline for completion and mapped out a plan to make it happen. While staying in communication with my leaders and the client, I was able to create a great system update in just a few short weeks."

In modern technology industries, consumer demand has led to high volume of work and high pressure situations to work on tight deadlines. To prove that you are able to handle high stress, high pressure situations on the job, your interviewer is looking to hear first hand how you handle this type of environment in your own words. As you answer the question, try to turn potential perceived stress into a positive by highlighting your personal skills that enable you to perform well in those situations. If possible, try to use specific examples in your answer.

"I am confident in high stress work situations because of my ability to adapt, communicate and be organized in my work. These skills came in very useful a few weeks ago when our support staff were experiencing an extremely high volume of help desk calls. My adaptability helped me go with the flow and handle items on at a time. My communication skills enabled me to quickly and efficiently call on needed support. My organization skills helped me be prepared for anything on that day and enabled me to work through tickets in a quick and efficient manner."

As the onsite consultant for our clients here at Mendix, you may be privy to confidential information or data. How can we ensure that you will hold client data security in the highest confidence?

"Having worked as a consultant for a large healthcare medical record software organization, I had access to thousands of medical records with each new client that we brought aboard. While often required to sign confidentiality and HIPAA agreements with each client, my own values would never allow me to compromise the secure data of a patient. If hired for this role, I would hold the confidential data with your clients in the highest regard and wouldn't hesitate to take all measures possible to ensure that data is secure."

The consulting world at Mendix will put your in a position to have access to client databases, applications and directories that could potentially contain sensitive data. Consultants have a responsibility to their clients to maintain that privacy. Be sure that your interviewer understands that you adhere to that responsibility by talking about past experiences where you have been exposed to and kept sensitive data confidential. It is important to talk about your own personal morals and values in your answer to this question.

"Successful consulting relationships with customers are built on trust and I value and respect the trust that my customers show my by maintaining all policies on confidentiality with each customer. My current role in the banking industry allows me access to the software of many banking institutions when I am onsite with them. When working with staff at bank branches, I don't discuss any personal financial data that I have access to even with them."

A huge part of our business here at Mendix is designing software for iOS. In this role, how would you steer away from retain cycles when using closures in Swift programming language?

"Because ARC handles most of the memory knowledge in Swift, I know ARC is prone to memory leaking and this can cause major issues in apps over time. The fix that I've used in my career to avoid retain cycles is using weak references in my coding."

This question allows your interviewer to assess your technical knowledge and skills in designing apps for iOS products in a very simple way. To successfully answer it, make sure that you can speak knowledgeably about the swift programming language and using closures to capture and store references within the software. To piece together everything for your interviewer, give a clear understanding of why retain cycles must be avoided in your processing.

Do you consider yourself stronger in C++, C#, Java, or Python?

"In my last company, we had a bit of an outdated tech stack and used C# and .NET. I found myself fully immersed in those technologies, but had a strong desire to learn more and become more familiar with modern technologies and how I can apply that in my career. That's what has me so interested in this role. Over the last year, I've taken courses in Java and C++, which I noticed you prefer. I've become proficient in the skills and in side projects, applied my increasingly strong knowledge. I'm probably strongest professionally in C# as that has been where my experience lies, but my passion and dedication is on the Java and C++ side, as I feel that's the more modern alternative. I'm excited about the possibility of applying that knowledge in a role at Mendix."

Before your interview, do some research to understand what tech stack Mendix uses so you can best prepare and highlight your expertise. If you aren't as strong in one of the skills you feel is necessary, be sure to explain how you've used it and how you are growing your knowledge to become better. Be sure to be honest in your answer, as the company will likely test your strengths.

"I am motivated and excited about this new opportunity because it will challenge me to grow in my (X) skills. I love soccer and enjoy spending time with my teammates. I am interested in continuing my education by studying (Y) to further my career."

What do you feel are the primary features and benefits of the Java programming language?

"When I started working with Java three years ago, the first huge benefit was the fact that the Java syntax was based on C++. At that time, I had a great working knowledge of C++ and my transition to Java was absolutely seamless. The other amazing feature that I've come to appreciate with Java is how robust the memory management is in exception handling and automatic garbage collection."

As a company that utilizes Java, Mendix and your interviewer want to make sure that you have an understanding of the Java programming language and they do so by asking this question. Obviously a language packed with unique features, talk about the features that you can speak the most knowledgeably about and tie your direct experience to.

What programming languages would you consider yourself fluent in?

"From the start of college, where software engineering grew into a passion for me, I've become very fluent in Java, JavaScript and C++. My current role has me working primarily with C++, but I pride myself on my ability and passion to learn new programming languages and would be able to do so if hired for this role with Mendix."

While this question gives your interviewer insight into the diversity of your programming language experience, they most importantly want to know that you are adaptable and able to learn on the fly if needed. Talk about the different languages that you consider yourself fluent in and, if possible, do as much research into Mendix as you can prior to your interview and try to speak to the specific languages that they work with.

"During my training to be an engineer and then in my current role since graduating, a majority of my experience falls within Python. My current role delves deeply into artificial intelligence and Python is awesome with this advanced technology. As I understand it from talking to another engineer here at Mendix, a requirement would be for me to learn Scala. Though I haven't worked directly with Scala, I believe my experience and willingness to learn would have me up and running in no time if hired for this role."

If hired for this position here at Mendix, would you be comfortable handling overall project manager responsibilities for new software development?

"Looking to join the team here at Mendix directly out of college, I feel very confident in my abilities to manage the entire scope of a new development project. I have leadership experience as my campus' president of the software engineering club. In that role, I developed skills that would help me utilize staff and resources in the best way possible. During my internship, I was exposed to the planning stages of new projects and I have a very good feel of estimating the budget and length of time needed to have a fully functional system."

As a skilled software engineer, you have all of the necessary tools in your bag to be a successful engineer at Mendix. This question is allowing your interviewer to get a better sense of your project management skills and people skills if you were to join the team at Mendix. In your answer, talk about your ability to estimate the time and cost of a project, the staffing needed and the overall scope of planning for a particular project. If you have direct experience in being the lead on a large development project, be sure to discuss that experience with your interviewer.

"I would absolutely be comfortable if tasked with project manager duties here at Mendix. In my last two roles, I have led successful projects that started with great planning and budgeting process and went through to completion with great people and processes in place under my leadership. While it's not a regular duty for me in my current role, I always welcome leadership duties."

Can you describe the software development lifecycle?

"Absolutely. In my last job, we leveraged the waterfall method, making sure we completed each phase of the project - and completed it on time and to the highest quality, before moving on. The software development lifecycle consists of 6 steps, starting with planning, of course, followed by implementation, testing, documentation, deployment, and maintenance. Every step is crucial to ensure we're producing a quality product and also maintaining that product to meet the changing needs and demands of our end users."

With this question, employers are looking to test your knowledge. They want to know how much you've participated in the projects you've been involved in to truly understand the software development lifecycle. The question may seem basic to some, but employers are expecting an accurate answer to know that they're hiring a true pro.

"I am new to my career in financial services and sales; however, I have taken an online course focused on cold calling. This course was incredibly helpful and I look forward to meeting and exceeding my targets with Mendix."

How do you feel cloud computing has positively impacted the software industry?

"Being in the software industry for over 20 years, I feel like the biggest impact that the cloud has had reflects directly to our customers in the software industry. In days of yore, we spent years working through software updates and releases. And now, I look to how we are continuously rolling out small scale, yet impactful, updates through the cloud and end users are able to see that impact the next day!"

While the reasons are plentiful as to how cloud computing has had a direct impact on developing and refining software for organizations, your interviewer is looking to hear which reasons you are willing to speak most passionately about. However you answer this question, try to either focus on the ease and accessibility for end users or cost savings for organizations in your answer.

"One commonly overlooked area where I feel cloud based systems have brought a major improvement is in analytics. Ten years ago, it took a lot of time and resources to pull relevant data to build analytics and visualization tools. Today, information can be automatically built to pull in the snap of a finger and that is something that I never take for granted in my work."

As you reflect back on your career to this point in your search for a new position, what would you say is your ideal work environment or culture?

"As I begin this job search now 15 years out of college, I'm looking for an employer that promotes and encourages innovation, new ideas and collaboration among all members of the team. From what I know about Mendix from speaking with others, you sound like a perfect match for what I am looking for in a career."

While using this question as a key indicator on how you'll fit with the team and the organization at Mendix, it will be very important for you to research as much as you can on the work environment at Mendix so you can match your priorities to that environment. If you have the opportunity to speak with an employee at Mendix prior to your interview, that can shed valuable information. In the end, the culture and value of an organization are often a key indicator of long-term success in a job, so make sure that you reflect your values into what the company values.

"With all of the companies that I have both worked for and consulted with in the past, I realize that a company culture is basically the personality of the company and I am looking for a new organization that really meshes well with my personality. I am a casual person that believes in hard work, teamwork and having fun on the job. As I embarked on a job search, I was so happy to see that Mendix was hiring because I believe our styles will fit perfectly together."

Tell me about the most interesting project you have worked on this year and the biggest thing you learned from it.

"In my previous role we were working on a variety of projects with fingerprint recognition software. One of the most interesting projects was a fingerprint-based ATM system. It was a test project for a large banking institution. In addition to learning a great deal about fingerprint recognition, I was also able to learn a lot about the critical relationship between software and security."

Discuss with the interviewer one of your recent projects that particularly piqued your interest. Did it stretch you professionally? What was the biggest takeaway for you from that particular project?

"I find the majority of the projects that I have been working on this past year to be very interesting. If I had to choose one, I would choose to work on the Uber app. Since I am still in my internship, I didn't have any major contributions; however, I learned a lot about on-demand apps and building a friendly user interface."

What is one thing that really tests your patience when dealing with your coworkers?

"As a person that values diversity and differences of opinion in the workplace, there aren't many things that grind my personal gears when it comes to my colleagues. The only real true test of my patience is a coworker that doesn't pull their weight in a team effort. When I've been in this situation in the past, I first seek to learn if the issue is a lack of training or knowledge. If it is, I take the necessary steps to help my colleague get on track. But if I find that it is due to a lack of effort, I talk to the person immediately in a professional manner. The sum is only as good as the effort of all of its parts and a team efforts requires everyone's maximum effort."

While on the surface this question may seem like your interviewer is trying to get you to talk negatively about a situation, it is really more of a test to see what can potentially drive you crazy on the job in a team atmosphere and how you handle those situations. In your answer, be honest about your pet peeves when it comes to coworkers and do so in a positive light. Then, expand on your answer by talking about how you handle those situations."As a person that values diversity and differences of opinion in the workplace, there aren't many things that grind my personal gears when it comes to my colleagues. The only real true test of my patience is a coworker that doesn't pull their weight in a team effort. When I've been in this situation in the past, I first seek to learn if the issue is a lack of training or knowledge. If it is, I take the necessary steps to help my colleague get on track. But if I find that it is due to a lack of effort, I talk to the person immediately in a professional manner. The sum is only as good as the effort of all of its parts and a team efforts requires everyone's maximum effort."

"Having been raised in a rural farm setting, I have always been a stickler for being on time and holding meetings to set lengths of time. While watching people show up late for meetings has bothered me internally because of how I am wired, I don't let it bother me on the exterior. We are all very busy in our lines of work and showing up a few minutes late is only normal from time to time."

In designing Android software, what is your experience using parcelable versus serializable within an app?

"Having written code for Android apps for many years now, I am very familiar with both serializable and parcelable methods. In my first hand experience, parcelable provides a much faster and better user experience so I will always strive to take the time to write custom code for marhsaling and unmarshaling to create less garbage objects within an app."

Because parcelable is optimized for Android to be faster and more customizable, your interviewer will be looking to hear that you are willing to put in the extra work to utilize the parcelable method to achieve better performance within the software that you design. Give your interviewer your thoughts on the differences between the two methods of passing object references to activities within an app that you design and make sure that they understand that you are ready to perform the work to utilize the parcelable method when necessary.

"Due to it being a standard Java interface and its ease of implementation, serializable interface is pretty commonly used. But, because it uses reflection, many temporary objects are created within Android apps and this creates a very poor user experience. When the parcelable interface was introduced for Android systems, I have extensively focused on its use and finished products have benefited greatly."

The next cloud engineer that we hire here at Mendix needs to be able build a system that can handle a high amount of traffic. How would you test our system's ability to handle large amounts of traffic?

"Cloud computing has certainly revolutionized the storage of high amounts of data and a key piece that cloud based systems bring to the table are their elasticity for handling large amounts of traffic. I see my job as building a cloud based system to scale horizontally to be able to handle the most data and traffic possible. To test systems, I've used a few different tools that were all very accurate prior to go-live."

This question allows your interviewer to gain insight into your thought process and ability surrounding building a cloud network that has an architecture that can handle large amounts of traffic without failure. Some key points to focus on your answer are your ability to match capacity to system demand and use horizontal scaling in the design of the system.

"In my current position as a cloud engineer, I have utilized internet scale services like Amazon S3 and Elastic Load Balancing to ensure that our cloud systems could handle large volume that fluctuate seasonally. Because of the great functionality of the internet scale services, internal testing wasn't necessary as we knew we were in good hands through those services."

If hired for this position at Mendix, what leadership skills would you bring to our team?

"I would say that my credibility is my best leadership skill. My openness and honesty suits me well when working among a team of individuals and this helps them gain trust in following my lead when working on projects. Another skill I would bring here to Mendix would be my ability to lead by example. I'm not afraid to take a risk in seeking innovation and I've been commended for this trait many times by my current manager."

While this position at Mendix may not hold the title of manager, supervisor or director, the organization firmly believes that employees that demonstrate key leadership qualities are better set for future career success. Aside from that, leadership skills help you work better as part of a larger team and with potential customers as well. Prior to your interview, think about one or two leadership qualities that you possess and talk in detail about how you've exemplified those qualities in the past.

"If you were to offer this position to me, you'd quickly find that my positive attitude is an inspiration to those that I work closely with. In my current job, we work under the constant stress of tight deadlines and my positivity can be infectious to help others maintain their focus when negativity can easily take over in most situations. I would say that my other strong suit as a natural leader is my ability to be fluid on a day to day basis. Sometimes our world can be monotonous and when change comes, most resist that change. For me, change is a chance to break the current mold and grow as an employee."

Our implementation consultants here at Mendix often face conflicts with our customers while onsite during implementations. What interpersonal skills do you use to handle conflicts with clients?

"Any time that I face a conflict in the workplace, I maintain my own personal composure by not taking things personally and keeping a smile on my face. After setting myself, I look to gain insight into the potential conflict by using my reflective listening skills and then problem solve from there. In this role, I would listen to the needs of the client and be empathetic in my approach with them. My ability to creatively problem solve would take over from there to help find a solution for the client."

In the software implementation process for large customers of Mendix, you will be working with top level managers and key decision makers onsite and more often than not, issues can arise. In your role as the implementation consultant, these issues come directly to you and your interviewer will be looking to hear how you will handle these issues to maintain both a great relationship with the customer and honor to the Mendix. In your answer, focus on finding solutions to issues that benefit both parties and talk about the important communication skills that you possess that will make this possible in any situation that you may face.

"The biggest skill that I would bring to the team here at Mendix as a consultant to clients would be my ability to express mutual respect to all that I work with. As an organization, Mendix has their own goals that I will be vital in helping to achieve. Your clients also have their own goals that can offer different greatly from yours. A sense of mutual respect allows me to put myself in the shoes of all involved and that really helps me find solutions that work for everyone."

How do you ensure that you have a healthy work-life balance in your career?

"As I am passionate about my career as a UX designer, I am also passionate about my family. Any moments outside of work are spent coaching my kids traveling baseball teams in the summer months and then spending as many weekends as possible on the ski slopes. These activities help keep me active, physically fit and keep my mind centered on what it truly important in my life when work weeks get stressful."

In the fast paced world in software and technology development, heavy work loads and potential on-call duties have created a lot of burnout in professionals. Your interviewer is looking to hear that you are cognizant of the risks of burnout and that you do what is necessary to maintain your own personal health and well being and that of your family as well. While you can use this time to talk about personal interests or hobbies outside of work, try to focus on how these items help keep you refreshed for the work that you'll be doing for Mendix.

"Having watched many of my senior colleagues over time suffer from work burnout that has caused marital issues and health issues, I make it a priority to maintain a healthy balance between my work and my home life. My free time is spent in the outdoors with my wife, whether that be on the lakes and rivers fishing or biking around town. I consider myself fortunate to be considered for a position here at Mendix because I know that you put a focus on your employees maintaining this healthy balance because the organization realizes how important this is to be productive."

What experience do you have in the different types of software maintenance?

"Being familiar with all four types of software maintenance, my most used method of maintenance in my current role is corrective. Based on bug reports from end users, I work through coding and logic issues to resolve issues in a timely and effective manner. In the maintenance I perform, I never hesitate to pick up the phone and contact customers to hear first hand about what they are experiencing. By doing this, they feel like they are an important part of the process and it reflects well on me and my organization."

As a reputable company, Mendix takes their software maintenance processes seriously and your interviewer is looking to hear that you are familiar with the four different types of software maintenance. Talk to your interviewer about any work you have done in the past with corrective, adaptive, perfective and/or preventative software maintenance. Use specific examples and make sure that your interviewer walks away from your conversation knowing that you understand the importance of proper system maintenance.

"In my current role, I'd definitely say that a majority of the maintenance work that I do is adaptive maintenance. Working in banking software that is used around the globe, I help perform system maintenance for changes in currency on a pretty regular basis. This work requires research and talking with end users to help adapt the programs for their use. If hired here at Mendix, I also have experience performing perfective, preventative and corrective maintenance on software as well."

Mendix embraces an Agile environment. Explain your experience in Agile methodologies and why you think it is important.

"The majority of my experience has been in an Agile environment. For ten years I have been personally responsible for leading agile teams, and I have helped define team goals and milestones. This approach is important to me as I see how Agile methodology helps employees deliver better products in less time. In my current role, team productivity increased by 34% once we introduced an Agile environment, and our on-time project rate skyrocketed another 18%."

The interviewer would like to understand the depth of your knowledge in Agile. The interviewer would also like to know if you work well with team collaboration, are responsive to stakeholder needs, and can work well with team defined milestones. Give a specific example of your experience.

"I especially want to work for Mendix because I have friends who have worked here before with really positive feedback on their experiences. I am looking for a positive work environment where I can stay for a long time to come."

In your current work, what are the important steps you take in the data validation process?

"As I embark on a data validation process in my current role, my first step is to roadmap a detailed plan to keep on task. I utilize benchmarks and the expectations of key stakeholders as my guide. Once underway, I validate the database and the data formatting to ensure that data is properly screened for its overall health. Then, by finishing with sampling, tests are performed to hopefully show that the data is useful within the system."

Depending on your training and your past roles prior to interviewing at Mendix, you may be familiar with one or two of the many trains of though regarding the steps of a data validation. Whatever formal process you are familiar with, be sure to check the boxes of discussing data screening and data verification as part of your process. Your interviewer will be looking to hear that you check those boxes as they are imperative in the software field.

"The most important steps in a data validation process are determining the data to sample, scouring the existing database and validating the final data format. My first step is to use my best judgment to determine if I will validate a sample or the entire data set. This determination is based on overall size of the set and the timeframe that I have to work on the project. Then, I take the time to screen data in the existing database to calculate the number of unique ID's and records to come into the system. Last, I have to verify that the source data matches the schema within the targe"

As a machine learning engineer, how do you avoid the curse of dimensionality in your designs?

"A common example that I use with people to explain complications in dimensionality is dropping a pin on a 10 foot straight line. This would be relatively simple to find. Next, if you dropped the pin in a 10 foot by 10 foot square, the task of finding the pin becomes more difficult. Adding a third dimension to make a 10 foot cubed area makes it all the more difficult to find the pin if placed within it. In bringing this back to machine learning, my job is to somehow make the three dimensional field that the machine will pull from easier to pull from. Last year, I was part of a team that developed a system for pulling public health data. We were able to set many variance thresholds that removed values that didn't change much from observation to observation. After careful testing, the system was able to pull information quickly and accurately based on these thresholds."

To effectively answer this question, it is important to first understand what dimensionality means in reference to machine learning and how it can curse a project. As the number of features increases in comparison to the number of observations within a data set, some algorithms struggle in pulling correct data. Your job on this question is to talk about ways that you can avoid the curse in your designs. Some possible things that you may mention and describe are feature selection, correlation thresholds and variance thresholds.

"As you can see from my resume, I've spent the last six years working in the electronics industry. Most of my machine learning work has focused audio data. To avoid the curse of dimensionality within the systems I've designed, autoencoders have been tremendous in pulling information. While a great amount of time and effort was needed to effectively train the systems, the work was well worth it in the end."

Tell me about your problem-solving skills. Do you enjoy analyzing and solving complex problems?

"In my last development position, I was responsible for front-line communications with end users. Third tier helpdesk staff would contact me with software bugs, and I was able to quickly and professionally respond to problems. I was able to reduce the bug backlog by 70%."

Software developers spend a great deal of time debugging programs. It is essential for Mendix to have someone experienced in quickly identifying problems and responsive in providing solutions. The interviewer would also like to gauge how you work with internal and external customers when problem-solving.

"If you did not have a good relationship with your previous boss: "I have had healthier relationships in the past with previous employers, but we did the best that we could. Our communication styles were very different which made it challenging at times."

What software analysis and design tools do you have familiarity working with?

"As my career and experience in software engineering has grown over the years, I've come to really appreciate and utilize these tools that are available. A great example of this would be my recent education and use of Structured English for designing insurance claim software for a large auto insurer. The simplicity of the structured decisions in the program were a perfect example of a program that could utilize the tool and the end product ended up very functional for our customer."

"I have great working knowledge in creating and reading data flow diagrams. To help with both our own sales staff and with customers, DFD's have been super helpful and I consider myself very proficient in creating them. I've also recently been introduced to decision tables to aid in product testing. I was working on a new system that involved some very complicated business rules and the decision table helped outline everything perfectly for our testing."
