Process
Applied online. The first step was completing a coding challenge on HackerRank.
Next was a one-hour phone screen. The interviewer seemed genuinely interested in my past projects. We spent the first 10 minutes talking about current and past projects. Then, I did a coding question on a shared coding environment. The environment compiled and ran code, so the code I wrote had to work.
Unfortunately, I didn't do so well during the phone screen and didn't make it past this stage.
