I applied on DevPost.com. The people I interacted with were friendly and they moved me along the process quickly.

I found the technical interview questions very challenging but totally fair. This is a mid-level position and I was a bit out of practice. Nothing they asked was unreasonable based on my level of experience. I did okay on my first-round technical interview and I did terribly on my second-round technical interview. Oh well.

They use HackerRank for technical interviews. The questions are confidential. They want you to be solid on data structures, algorithms, and big-O notation.

First round was an automated test: 90 minutes and four questions. Second round was using an online shared document to work through a coding exercise one-on-one with one of their IT professionals.
