A screening interview with Amir Hadadi, Chief Software Architect at Outbrain. I had 1 question that I aswered, but the answer was different from the one he suggested. There was no chemistry and I doubt I passed it.

The first round was a take-home assessment with two actual coding questions, got the homework right after a brief talk with the recruiter. The question itself wasn't quite difficult but did require sometime to think about runtime complexity, code readability, optimizations, tests etc. The next week I was invited for onsite interview, 5 rounds in total, 45 minutes each round. Spoke with the team manager and the engineers (from different teams), the interviews include system design questions, coding on whiteboard, culture fit, and conversation with HR. The interview ended with a tour in the office, very friendly and nice interviewers. Awesome work station for engineers also -- macbook-pro with two 27'' MAC monitors. Got offer after a week.
