If you can, please provide your thoughts on the function of managed object context in developing iOS apps and software.
While the core data framework and the managed object context may seem pretty easy to comprehend and simple from a first look, a deeper look into managed object context shows that it can be misused to the point where obscure bugs can enter the system. Give your interviewer your own personal insight into the purpose of managed object context and how it works behind the scenes to help an app properly run.
Ryan's Answer #1
"In my current work, I work with both main queue and private queue manged object contexts. It is important that I avoid non user related data processing on the main queue of an app that I am developing. In times where this has happened in the past, the user interface becomes unresponsive and crashes. As well, I work to avoid instances passing between the main and private queues to avoid corruption of data within the app."
Ryan's Answer #2
"Knowing that a managed object context's job is to manage a number of records within an app, my job is to successfully manage each object within the app and assign it to a correlating context within the app. I have to consider the persistent store coordinator and code the app to fetch requests from the correct one."

What programming languages would you consider yourself fluent in?
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 WePay as you can prior to your interview and try to speak to the specific languages that they work with.
Ryan's Answer #1
"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 WePay."
Ryan's Answer #2
"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 WePay, 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."

Here at WePay, we utilize feasibility studies with our customers to consider all impacts of a new system for them. Do you have familiarity working with feasibility studies in your work as a software engineer?
To properly answer this question, make sure you understand the reasons why feasibility studies are important. In essence, a feasibility study helps to determine if conditions are right to implement a project. The study looks at economic, operation, legal and technical aspects of the project to determine if moving forward with the project is best for all involved. If you have experience in the studies, talk about a specific time that you utilized a study, the steps you took and explain why it was important to do in the end. Make sure that your interviewer walks away from the interview comfortable with your ability to utilize feasibility studies in your work.
Ryan's Answer
"I do have familiarity with feasibility studies throughout my career as a software engineer. On a current project that I am working on, we utilized a study to analyze if the project we were tasked with could use current technologies available to us while meeting a timeline for completion. On my end, I had to spend time researching the resources that were available, gauge their functionality and come up with a plan for action based on that. Where the project stands today, we are on pace for delivering a revolutionary system for a large security industry customer."

Give an example of a time that you used a universal design practice in your work as a UI or UX designer. Why was it important to do this?
In the technology, software and mobile app fields today, accessibility is a huge topic. As a designer with WePay, you will be expected to help create products that are as accessible as possible to as many end users as possible. In this two part question, talk about why you feel that universal design is important in the work that you will be doing with WePay and then really sell your ability to do this by giving an example of a time you used a universal design in your previous work.
Ryan's Answer #1
"From a very high level, the business success of a program really relies on being universally designed. If we pigeon hole ourselves, a product will only reach a very limited group of end users. But taking that a step further, universal design is the morally right thing to do to help reach people that may not have access to the average program design. Last year, I was part of a project that utilized a voice user interface for users that were deaf or hard of hearing. This simple yet effective design was a huge win for our current customers and in helping drive new business with our groundbreaking software."
Ryan's Answer #2
"Early in my career, the best piece of advice that I receive was from an experience designer and she said that when UX doesn't consider all potential users, we are no longer working on the user experience. We live in a very diverse world and the programs that I've designed for in the past have certainly had the goal to reach a wide audience. With your financial products here at WePay, this same philosophy applies. Last year, based on some feedback from current customers, we switched our design to include a strong color contract to make the system much more user friendly to color blind users. This was both a simple and very effective change to enhance the look of the program."

Do you consider yourself stronger in C++, C#, Java, or Python?
Before your interview, do some research to understand what tech stack WePay 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.
Ryan's Answer #1
"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 WePay."
Ryan's Answer #2
"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."
