There was an initial phone screen which lasted for about half an hour with an HR who asked me basic questions about my background. She tried to discover if I had FE/BE preferences even though the role was full stack. She was a little vague on compensation but I chose to proceed. This was followed by a coding challenge that I did on one of the platforms. Lasted for about 2 hours and it was concidered a good signal if you could get it done sooner (a little weird). They just wanted working code, they don't care about polish or quality at this stage. I guess they work in a very iterative fashion. This was followed by an onsite which consisted of 5 parts. I was required to bring my laptop. During the interviews I would use it to write code, which I thought was pretty good, thought at that stage I was equally comofortable writing solutions on the whiteboard. First interview consisted of a couple of alrgorithmic questions, see below. They were not very hard. Second was design review with 2 guys. It was well conducted and interesting. Third part was with an engineering manager or director for whom I didn't feel that she was listening to me. She had a laptop and I'm pretty sure she wasn't taking notes but sending emails/slack. This felt really bad and I felt I didn't establish any sort of contact. Last part was about database schema design and querying. See below for details. All the guys seemed smart, they were asking good questions and I felt the bar was high which is a good thing. Was rejected with a clumsy and vague email sent from a noreply email address (very poor).I would've thanked them but... noreply email :D. Rating the process as positive because most people seemed smart and polite, baring select few.
