First, I received a coding problem as a 'homework'. I would say the problem was fairly easy. One week later, I had a phone interview with a manager. It lasted 15 minutes, we (briefly) talked about my last experience, my solution to the problem, I even had some time to ask questions about the position. One week later, I got an email saying I was not selected for in-person interview as I did not detect issues in my solution - No, I only explained my choice and proposed scalability improvements, which did not trigger any interest from the interviewer as he did not question it. Since they recorded the phone interview, and the company praises on its website its transparency, I gently requested a copy of the record for my personal review. I never received anything. Their principles are great, I am still wondering about the rest...
