e-Zest Solutions Interview Questions

  1. 1.

    At e-Zest Solutions, we take security risks very importantly in our products. In your experience, what are the biggest security risks in software and what is your experience in any prevention methods?

      As an expert in software industry, you are obviously aware of the many security risks that systems face in this day and age. For your answer to this question, talk knowledgeably about the security risks that you are most familiar with combating in your day to day work. Explain why the posed risk is important to combat against and talk about the methods you used to minimalize risk in the finished product.

      Ryan's Answer #1

      "As I'm fully aware, cyber-security has become a very important issue over the past ten years. In my current role, our biggest security risk is injection of code used by hackers to access information in our web applications. To help prevent any risks associated with injection, we've implemented the use of a safe API and using specific LIMIT and other SQL controls within queries to prevent loss of records in case of an injection."

      Ryan's Answer #2

      "In the healthcare field where I currently work, broken authentication vulnerability has allowed attackers to hack into electronic medical records and gain control over those systems. This type of attack potentially puts hundreds of thousands of people at risk within a given system. We use many methods to prevent this type of security risk. First, we take the time to properly test the code before rolling out new updates to software. We also utilize very detailed external security audits. Other details we have implemented have been multi-factor authentication processes and recommendations to align password requirements with the NIST guidelines."

  2. 2.

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

      As a company that utilizes Java, e-Zest Solutions 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.

      Ryan's Answer

      "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."

  3. 3.

    If hired here at e-Zest Solutions to develop iOS and Android software, when would you use a fragment rather than an activity?

      In the development of apps for both iOS and Android, using code to create an activity versus a fragment is a highly debated topic to this day. For this question, your interviewer is looking to hear that you understand what the differences between the two are and when you feel that using a fragment is the proper direction to go. Make sure to speak to the high level overview of what an activity does to an app versus fragments.

      Ryan's Answer #1

      "As a best practice in my development of Android apps in the past, activities are really the complete screen that a user experiences as part of the app. Fragments are really small sub activities that take place within the activity. Because fragments within an app have their own life cycle and receive their own input events within the app, there are specific times where fragments make the most sense to use in development. In my experience, I always use fragments when the app is working with UI components that are going to be uses across multiple activities within the app. As well, fragments have also served very well when using swipe views within the app."

      Ryan's Answer #2

      "In the past year, I honestly don't recall designing a new app that ran solely on an activity alone. The fragments are almost necessary today to bring life to an app. I use retained fragments to persist across activity restarts within the app and this helps make a user friendly experience for our end users."

  4. 4.

    When would you utilize a trigger within Oracle to execute a function automatically?

      To answer this question, it is important to first have an understanding of what a trigger is within Oracle. Simply defined, a trigger is a named block stored within the database that executes on its own when a certain even takes place. While you talk about your understanding of what a trigger is, be sure that you explain that you understand how to create a trigger in Oracle and that you understand that proper situations to utilize them in.

      Ryan's Answer #1

      "In the current work that I do in Oracle, I utilize triggers to prevent invalid transactions within the software that I am working with. I have a full understanding of how to write create trigger statements using declaration statements, executable statements and exception handling statements to set the appropriate triggers. If hired for this role here at e-Zest Solutions, you could have full confidence in my ability to utilize triggers within Oracle."

      Ryan's Answer #2

      "With my two prior years spent working on Oracle, I have written database triggers using insert, update and delete statements that are issued against a table. These database triggers allow our end users to be able to reap the benefits of the triggers. The instances that I've utilized database triggers have been for pulling statistical information from the tables within the system."

  5. 5.

    At e-Zest Solutions, we rely on a full team effort to deliver top quality products to our customers. Tell me about a time that you worked well as part of a team. Are you comfortable in a similar role here?

      While this potential role with e-Zest Solutions will require your to be an independent worker that can think on your feet, you will also need to work as part of a larger team that is working toward one common goal. Because of this fact, your interviewer will want to hear that you thrive in an environment where you work with team members from other disciplines than you are trained in. In your example, stress to your interviewer that you have excellent communication skills and that you fully understand that every person on a team plays a vital role in the organization's success.

      Ryan's Answer #1

      "Throughout my career, I've always enjoyed working as part of a larger team on the job and this personal enjoyment started with my love of and participation in team sports like baseball and basketball. Growing up playing sports, I learned that each team member brought a unique skill set that could help us achieve our goals. Through a great coaching staff that knew how to make these individual skills shine, this same philosophy holds true for a team that is looking to design a new software system. I know that my skills as an engineer are just part of the final product and I work very well with designers, architects, analysts and sales to help build the greatest system possible."

      Ryan's Answer #2

      "I am a people person by nature and my current role has me working very closely with our engineering and design staff on writing technical manuals for our products. While I certainly can handle long days at my computer in solitude, my desire to work hand in hand with others really sets me apart from my peers in this field. I have excellent verbal, listening and written communication skills that, if hired here at e-Zest Solutions, your entire team would appreciate from my first day on the job."

  6. 6.

    If you were asked to review a colleague's code that they had written, what key things would you look for?

      For this question, your interviewer will obviously be looking to hear that you have adequate knowledge when it comes to coding processes. But most importantly, your interviewer will be looking to gauge your ability to be a team player and focus on the bigger picture when working on a project. In your answer, focus on your attention to detail and your ability to help others when needed.

      Ryan's Answer #1

      "As an experienced software engineer, I fully expect my colleagues to reach out to me for my insight and I never hesitate to provide open and honest feedback. When asked to do this, my main focus is ensuring that the code is readable and functional. If there are lines of code that need to be removed, I don't hesitate to let my colleague know that while also giving them feedback on why I feel it is unnecessary."

      Ryan's Answer #2

      "When I'm asked to do this in my current position, my main focus is on regulatory requirements that were put in place for the project and security issues. I work with a team of great engineers that are very efficient coders and these two areas are most often overlooked."

  7. 7.

    Talk about a time when things didn't go as planned on the job. What was the situation and what allowed your to persevere in that situation?

      As a professional in the tech industry, you have likely had a project that failed, a promotion that passed you over or a meltdown occur at some point in time. Realizing that your interviewer fully understands and expects that failure happens, talk openly and honestly about a situation where you experienced failure or failed plans. Most importantly in your answer, focus on how you overcame the particular situation and discuss lessons that you learned moving forward that you can bring to this role at e-Zest Solutions.

      Ryan's Answer #1

      "A couple of years ago in my first role as a UI designer out of college, my team was tasked with coming up with a very short notice proposal for a potential high end customer. With a week turnaround time, I set right to spending my time gathering information on the company to build a mock design. When the proposal was submitted, I found out that the potential customer scoffed at my idea and the customer went with another organization's proposal for their use. The biggest piece of feedback that I got was that the UI design just wasn't conducive to the type of customers they were expecting. From that point forward, whether it has been with short notice or long-term products, I take the time to communicate with key decision makers from clients to gather information for making my design as user friendly as possible."

      Ryan's Answer #2

      "Last year, I was working on a large scale project that put me face to face with a key customer. After traveling onsite with the customer to spend time with them, I exchanged contact information with two of the key decision makers. In the weeks following, I was sending them follow up emails with our business proposals and was getting frustrated at the lack of response from the clients. After my manager had questioned the viability of the potential customer, I picked up the phone and called them directly. It turns out that their responses back to me were being sent to a junk email folder that I neglected to consider. I apologized for the mistake, took action quickly and we came to a great agreement on future business together. After having a laugh about it with my boss, I now incorporate diligent communication follow ups both by phone and email with customers while also regularly checking all email inboxes."

  8. 8.

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

      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?

      Ryan's Answer #1

      "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."

      Ryan's Answer #2

      "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."

  9. 9.

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

      The world of software engineering has greatly benefited from advancements in computer aided software engineering tools. Because e-Zest Solutions 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.

      Ryan's Answer #1

      "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."

      Ryan's Answer #2

      "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 e-Zest Solutions."

  10. 10.

    Would you say that you are a goal oriented on the job? What would I be able to do as your manager to help you achieve your goals if hired here at e-Zest Solutions?

      At the heart of this question lies your interviewers desire to see what motivates you as a potential employee at e-Zest Solutions. Make it clear to your interviewer that you certainly are motivated by on the job goals and do this by using an example of a time where you were motivated by and achieved a goal. Then, think deeply about the type of manager that you like to work for in terms of goal setting and helping our achieve your goals. Let your interviewer know what type of management styles you appreciate the most while being open to any style.

      Ryan's Answer #1

      "I would definitely say that I am goal oriented on the job in wanting to contribute any way that I can to the overall benefit of the organization. In my current organization, our leadership focuses on overall sales numbers at the end of the year. To help achieve these goals, our department creates our own goals to help achieve the sales numbers needed to succeed. Last year, one of those goals was to be as creative as possible in our user experience design processes. With the launch of an exciting new app midyear, sales numbers skyrocketed and our department was instrumental in that. For me, it was important that we determined our goals as a team with the final stamp of approval from our manager. While this style of management really helped motivate me, I can thrive under any management style as long as expectations and goals for my work are clearly set."

      Ryan's Answer #2

      "For me, my day to day work is much more meaningful when I have goals to work for. In my current role, we have set timelines for our projects and this helps lay the framework for our goals. If hired for this position, my expectations of you as my manager would be to have goals clearly defined and a supportive atmosphere to be provided to work within."

  11. 11.

    What SDLC models are you familiar in working with?

      As a software engineer, you are very familiar with the software development life cycle. For this question, your interviewer is looking to hear what models you have worked on in the past. While there isn't necessarily a right or wrong answer to this question, try to show your flexibility to working with different SDLC models by bringing up your past experiences. Then, show you have knowledge of different models like the waterfall model or agile model. It is also a good idea to use this question as an opportunity for you to learn more about e-Zest Solutions by asking your interviewer which model they work off of.

      Ryan's Answer #1

      "During my training in software engineering and in my early career, the waterfall model was the standard. In this model, each phase of the development process happens in a set order and projects using this model are easily managed. But over time, as the development projects that I have led have become more complicated and intricate, I have implemented the spiral model. This model has allowed the ability of end users to give feedback early on and often during development and helps to build a more customized product to our customers."

      Ryan's Answer #2

      "In my current position with XYZ Company, my department utilizes the agile model in development life cycle. Since our products are so tailored to the needs of our customers, we get a working product very early on in the process and then I work hand in hand with customers to fine tune the software moving forward. It is a very effective model that has built a great reputation for our software among customers. I also have familiarity working with the iterative model and it has similar advantages to the agile model. If I were hired here at e-Zest Solutions, can you expand on what models you use here in your software development life cycle?"

  12. 12.

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

      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.

      Ryan's Answer

      "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."

  13. 13.

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

      As a skilled software engineer, you have all of the necessary tools in your bag to be a successful engineer at e-Zest Solutions. 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 e-Zest Solutions. 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.

      Ryan's Answer #1

      "Looking to join the team here at e-Zest Solutions 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."

      Ryan's Answer #2

      "I would absolutely be comfortable if tasked with project manager duties here at e-Zest Solutions. 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."

  14. 14.

    In your experience in software testing, would you consider yourself proficient in both testing and debugging processes?

      As a reputable provider of software, e-Zest Solutions relies on their software testing engineers to both test and debug their products when necessary. Make your interviewer aware that you are knowledgeable on both processes by briefly explaining each process as you've worked on them in the past. Then, talk about your openness to working both testing and debugging processes if hired for this position.

      Ryan's Answer #1

      "Yes, I definitely would consider myself proficient in both testing and debugging software. My current role that I've held for four years since graduating from college has exposed me to both processes. In testing, I use known conditions and predefined methods to test for expected outcomes to find errors within the system. I utilize testing prior to new software rollouts. The debugging process happens to already released software that has had issues and comes with unknown conditions and unpredictable outcomes. In this process, my goal is to find the cause of the error to fix it efficiently and effectively to roll an updated program back out to end users."

      Ryan's Answer #2

      "While a majority of my career has been focused on software testing, I am very familiar with debugging processes as well. If hired for this position, I would take the time to focus on debugging processes to bring myself up to speed while being able to hit the ground running on testing processes."

  15. 15.

    The software we develop here at e-Zest Solutions requires you to have working knowledge of both privileges and roles within Oracle. Can you talk about your knowledge and experience of both within Oracle?

      On the development end of software, your role at e-Zest Solutions will require you to have knowledge of the differences between user privilege and role. Your role will put you working with end users on the two roles and explaining your knowledge of the two will be important to your interviewer. Give a basic understanding that privilege relates to the right to execute SQL statements and another user's objects as defined by Oracle. Then talk about roles being created by administrators to grant privileges to their users.

      Ryan's Answer #1

      "In my current role, I have great working knowledge of both role and privilege within Oracle as I work with the system administrators of our end users very closely. I work with them on using the grant and revoke commands to define the roles or their users and grant permissions within their system. To do this, I have to gain strong knowledge on the different people that are allowed access to the system and what they will be doing with their access."

      Ryan's Answer #2

      "As you can see from my resume, it has been a few years since I've worked directly with Oracle but I do have great working knowledge of the system. To best explain my knowledge, privileges control the ability to run SQL statements with the database and my role has been to outline those privileges for our end users. Then, roles group together different privileges for each end user. In my past work, I'm most familiar with creating the different roles within the system and then working with key decision makes with our end users to grant the privileges to the roles we defined."
