Plex Systems Interview Questions

  1. 1.

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

      While this position at Plex Systems 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.

      Ryan's Answer

      "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 Plex Systems 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."

      Ryan's Answer

      "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."

  2. 2.

    If hired here at Plex Systems, what do you feel would be the biggest hurdle for you to overcome from the start?

      The key to answering this question with confidence starts with understanding that you are interviewing with Plex Systems because your interviewer feels that you are a strong candidate for this position. What your interviewer is focusing on with this question is how they could be of most help to you if hired for the job. So, take the time prior to your interview to think about an aspect of the position that would be the most difficult for you to overcome to be up and running at full speed and then take time to explain how you would plan to overcome that hurdle if hired. This structured answer will tell your interviewer that you have put thought to your potential shortcoming with a plan of action.

      Ryan's Answer

      "As you can see from my resume, I don't have any direct working experience with the financial industry and I would see that as my largest learning opportunity if offered this position. Like I did with my current job in the healthcare industry, I would take the time to learn the basics of the industry that would help me design the most intuitive user interfaces in the products here at Plex Systems."

      Ryan's Answer

      "Being a team player by nature, I've always considered my first challenge at any new company to be the task of getting to know my colleagues, their work preferences and their work styles. In the same breath, I want them to know who I am and how I best work as part of a team with them. To accomplish this, I would take the initiative to set one on one meetings with individuals that I didn't get to touch base with during my orientation process to get to know them better."

  3. 3.

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

      As a reputable company, Plex Systems 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.

      Ryan's Answer

      "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."

      Ryan's Answer

      "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 Plex Systems, I also have experience performing perfective, preventative and corrective maintenance on software as well."

  4. 4.

    Our cloud computing at Plex Systems requires our experts to take proper security measures in their work. What security measures are you familiar with utilizing in a cloud platform?

      As with any server or database storage, unique security risks are posed to organizations that have moved their data and applications to the cloud. At Plex Systems, part of your role will be to ensure that all security measures are in place with the organizations data in the cloud and your interviewer is looking to hear that you are familiar with diagnosing security risks and taking action to prevent them with this question. Talk about your knowledge of the different cloud service providers and other security measures that you are familiar with taking in your work.

      Ryan's Answer

      "For me, the planning stage of the cloud deployment process really sets the groundwork for security in a project. In my current role, each project adopts a cloud framework that suits the project the best. This framework is the base for our security measures in the cloud. From there, I always look to utilize a cloud service that encrypts our data and take all measures to steer away from storing sensitive information within the cloud. Last, as with any project, I help implement strict testing measures to check on the security of our cloud operations."

      Ryan's Answer

      "In my current role, the biggest security risks that we face are loss of sensitive data and malware infections. To take all security measures possible, our first plan of attack for security is to ensure that all of our data is backed up locally with electronic copies of data. To prevent malware in all ways possible, we have implemented a strict password strength policy and we install anti-virus software in our own equipment and recommend that customers do the same as well."

  5. 5.

    How would you handle a situation where a colleague was being very difficult to work with?

      In the team based atmosphere at Plex Systems, departments with different skills and backgrounds can often see things from different points of view and these situations can cause some internal conflict between coworkers. With this question, your interviewer is looking to hear how you handle situations where you are working with someone that can be seen as difficult. To give them the sense that you are able to work through conflict in a professional and sensible manner, try to talk through how you handled a conflict at work previously in the past and highlight the interpersonal skills that you used to help make it a positive situation.

      Ryan's Answer

      "In all honesty, any great work atmosphere that I've been a part of in the past has involved conflict between colleagues. In situations I have witnessed, conflict has stemmed from very open-minded people giving their two cents in particular situations and two people not seeing eye to eye. This happened recently to me in the planning phases of a new project. On of our UX Designers and I had a disagreement on the final layout of a new software roll out we were planning. It worked best for both of us to talk about our ideas and list the pro's and con's for our ideas. I kept an open mind to learn from her point of view and she did the same to me on my end. This led us to come up with a great compromise in the end."

      Ryan's Answer

      "Last year, we had a new engineer join our team that was hired on from his internship with us. From his first day, he made it very evident that he would only handle certain tasks within our team and only work on certain projects. As his mentor to help get him up and running, I sat him down and discussed the expectations of each of our engineers as part of our larger team. I explained to him that our approach was not to pigeonhole ourselves into smaller tasks, but rather be well rounded engineers that could handle any project and be able to cover for each other if needed. He really appreciated this approach when I explained the benefits for his long term career goals with this approach. This example shows my approach to being very direct with people that I have a conflict with in the workplace and doing so in a very professional and educational manner."

    In your mind, when is monkey testing the most effective in testing new software?

      By utilizing random inputs to check the behavior of a program, monkey testing has its time and place in the software testing process. For this question, your interviewer is looking to hear that you have an understanding of the theory behind monkey testing and how you would look to put it to work at Plex Systems to test their products.

      Ryan's Answer

      "In my experience, monkey testing has been very effective in load testing and stress testing new software as standard testing methods couldn't do this without a lot of extra work. Because of the adhoc approach to the testing, load and stress on the software was most highly gauged through monkey testing."

      Ryan's Answer

      "Because monkey testing is able to find unique bugs that standard testing won't find, I've found it to be very effective for testing new pilot software programs that are reaching new bounds. At my current job, I helped design a brilliant monkey testing process that utilized user behavior to look for certain probabilities of bugs within our systems that we were designing."

  7. 7.

    Plex Systems hires developers with a strong understanding of object-oriented programming. Discuss your knowledge in this area.

      The interviewer would like to understand your knowledge and experience in object-oriented programming languages, such as Java, C++, Python, Visual Basic, Ruby, etc. Walk them through your experience, being sure to highlight any specialized training or coursework. If you took on a significant project using an object-oriented programming language, you could give an overview of that work.

      Ryan's Answer

      "When I was hired for my first development position five years ago, my employer provided in-depth programming and development courses. I trained in Java and C++, and over the years I have gained expertise by using these applications for my development roles."

      Ryan's Answer

      "Here are some other essential characteristics that you can draw on:

      - Disciplined
      - Intuitive
      - Takes Initiative
      - Responsible
      - Positive Attitude
      - Solid Communicator"

  8. 8.

    What do you consider to be a good litmus test for when you would automate a test process for a new system versus testing manually?

      As your role with Plex Systems will look to help further their automate testing processes for new systems, you will need to have a good sense for when automation makes sense and when it does not. Reiterate your sense for this to your interviewer by sticking to the high level response that repetitive tasks, as are common with large software companies, are prime candidates for automation whereas one time test cases are not.

      Ryan's Answer

      "Having been in automation in both manufacturing for many years and now software for the last three years, a common misconception among people is that automation can help improve any situation and that couldn't be further from the truth. The amount of time, effort and resources that goes into an automation process makes it ideal for repetitive tasks and tests that have multiple data sets. If a testing process calls for unique and one time process, it would make the most sense to run that process manually."

      Ryan's Answer

      "I"n my current position, most of the automation testing that I design is in program sanity testing. These automated tests work great because they run on similar systems following changes in code to ensure that no bugs remain in the system. If our group of engineers are working on unique, one off type projects, my automation processes are not utilized."

  9. 9.

    Here at Plex Systems, we ask our test engineers to follow specific QA protocols. What role do you feel QA plays in software development and testing?

      As an experience software testing engineer, quality assurance should be ingrained in your brain and your interviewer is looking to get a sense of your personal feelings towards it in your work with this question. In your answer, be sure to highlight QA's importance in reducing errors, maintaining specifications, testing failure parameters and preventing defects from occurring. In the end, make sure that quality is your mantra in the eyes of your interviewer by giving an example or two of how you put QA in the forefront of your work.

      Ryan's Answer

      "As a test engineer, I take great pride in my role of ensuring that systems go out to consumers as error free as possible. In my current role, I take the time to learn all of the system specifications that are laid out by our design engineers and customize my testing to follow those specifications."

      Ryan's Answer

      "In my work throughout my career, quality assurance in my testing was an every minute of every day job on my part. While creating effective testing processes on new software is extremely important in following QA protocols, the recording of defects, issuing of reports and assisting the designers on fixing issues are equally important parts of the process that I'd love to let shine here at Plex Systems."

    What data cleaning methods are you familiar with and comfortable using if hired for this role at Plex Systems?

      To improve data quality and increase overall productivity of a system, Plex Systems relies on their data analysts to use data cleansing methods to ensure quality data exists in their software. Be open and honest with the ways that you've helped ensure quality and accurate data in the systems that you've worked with while also showing that you have an open mind to learning and utilizing more methods if hired for this position.

      Ryan's Answer

      "In my current work, I use a very methodical fashion in cleaning data for finished systems. My first step is to remove duplicate and irrelevant observations within the data. Then I scan the data to remove extra spaces, convert numbers stored as text into numbers and remove duplicate data. These steps help ensure clean and accurate data and I never overlook them. If hired for this position, what methods does the current data analyst team her at Plex Systems utilize?"

      Ryan's Answer

      "I am familiar with many methods used in the cleansing of data. The initial monitoring of errors within a system is very important to identifying where errors occur and give insight into how to fix corrupt data. I have utilized the tools within Domo software to validate data accuracy and scrub for duplicate data in my processes as well. Being very proficient in data analysis, I'm very open to learning new methods as well if hired for this position."

    The next cloud engineer that we hire here at Plex Systems 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?

      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.

      Ryan's Answer

      "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."

      Ryan's Answer

      "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."

  12. 12.

    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 Plex Systems?

      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 Plex Systems 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.

      Ryan's Answer

      "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 Plex Systems."

  13. 13.

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

      Plex Systems 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.

      Ryan's Answer

      "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."

      Ryan's Answer

      "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."

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

      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.

      Ryan's Answer

      "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."

      Ryan's 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."

    How have you handled obstacles that you've faced during information gathering processes in your time as a technical writer?

      To successfully document and write about software products, information gathering from subject matter experts will be a key part of your process if hired for this role at Plex Systems. As you have likely experienced during your career, the information gathering process can be one of the most painstaking processes within the life of a project. For this question, your interviewer is looking to hear what obstacles you have faced in this situation in the past and how you handled those situations. This will give them insight on how you will work as part of a larger team in handling these perceived obstacles if hired for this position.

      Ryan's Answer

      "Because the information gathering phase is a vital step in my finished projects, I take the time to meet as many credible sources as possible. This includes design engineers, automation engineers, product designers and many other folks and the biggest hiccup that I usually come across is coordinating time with folks that have busy schedules. To help minimize the total time frame for info gathering, I am very direct in my communications to key leaders that I want to meet with to finish a project and my directness is always taken well. Like any obstacle we face in our work, I find that being upfront and direct is the best manner for handling them."

      Ryan's Answer

      "I'd say that one of the more common obstacles that I have faced in my current role as a technical writer is a lack of expectations from the experts that I consult with through the process. To better this over time, I have created a set of general expectations that I provide to people ahead of our meetings that help them prepare information ahead of time. This approach not only helps me get more relevant information up front, but also helps speed the information process up significantly."
