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."

If hired here at Gentex, 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 Gentex 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 #1
"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 Gentex."
Ryan's Answer #2
"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.
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 Gentex 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."

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."

If hired for this position at Gentex, what leadership skills would you bring to our team?
While this position at Gentex 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 #1
"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 Gentex 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 #2
"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."
