6.
Here at QNX Software Systems, we strive for continuous delivery and continuous deployment with our software. Are you familiar with these processes in your current work?
In the industries that QNX Software Systems works in, updates to software are vital to end users for them to stay at the forefront of their business. To ensure that updates happen as quick and smoothly as possible, QNX Software Systems utilizes continuous delivery and continuous deployment for their customers. For this question, talk about what you know about these processes as a software architect, why they are important and what experience you have with them.

Ryan's Answer #1
"In my current role, we utilize a 100% continuous deployment process with our end users when we role out new changes to existing software. We use automated testing in our process to validate that code changes are correct and able to be deployed without issue. Once validated, changes are automatically rolled out to our end users. Having once utilized a continuous delivery system, I am very appreciative of working in an environment utilizing continuous deployment as it negates any need for human intervention in the roll out."
Ryan's Answer #2
"In my current position, we've slowly grown from a continuous integration process to a continuous delivery process. I love the automated testing process when we are looking at rolling out new changes to existing software and my role as the architect for our projects puts me in the drivers seat for sending out these changes.

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."
8.
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 QNX Software Systems 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 QNX Software Systems, can you expand on what models you use here in your software development life cycle?"

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."
10.
What do you feel is one of the top issues that is faced by data engineers today?
Being in the midst of the greatest technological revolution in the history of man, data engineers face many difficult issues in the work that they perform on a daily basis. While there are many directions that you can go with this question, be sure to focus your answer on something that you can speak passionately about. If you can research a common issue in the industry that QNX Software Systems works in, you may likely score some bonus points with your interviewer.

Ryan's Answer #1

Here at QNX Software Systems, I can only imagine how big of an issue that is in the healthcare industry. I have a lot of experience with cloud based data storage and also server based storage."
Ryan's Answer #2
"In my recent experiences, continuous, real-time integration is an issue that we will face each and every day moving forward. The need for fast paced information is certainly to blame for this. To stay on top of the continuous integration landscape, I am happy to hear that new and improved systems are being created to stay more real-time and up to the minute. Here at QNX Software Systems and working in the financial industry, how have you seen this need for real-time data impact your products?"
11.
As a machine learning engineer, how do you avoid the curse of dimensionality in your designs?
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.

Ryan's Answer #1
"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."
Ryan's Answer #2
"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."
12.
What would you consider your technical specialty?
Do you have any particular areas of interest or ability? Talk to the interviewer about your strengths and be sure to highlight any specific skills that you excel in. It's a great idea, if you can, to highlight particular skills that may be listed on the company's job posting/job description. If there is a related area of interest where you'd like to expand your skills, you can mention those as well.

Ryan's Answer #1
"Computing and Network Communications has always been a solid area for me. I have a big interest in how network communication improves our daily lives and our overall business efficiency. I see that you are looking for team members who are experts in network communications which is what caught my eye when I first saw your job posting."
Ryan's Answer #2
"I have been focusing my career on becoming a cloud integration specialist although I do have cross-platform app development expertise as well."
13.
If hired for this position here at QNX Software Systems, 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 QNX Software Systems. 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 QNX Software Systems. 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 QNX Software Systems 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 QNX Software Systems. 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.
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."
15.
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 QNX Software 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 #1
"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 #2
"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."
