Initially, I had a Skype interview where I shared my screen with the interviewer. The question was fairly straightforward, about allocating and deallocating servers, and I wrote unit tests for these as well.

To all those who wonder why they got rejected despite all their unit tests passing: I read somewhere online that this initial round is really just about testing your intuition for what makes good code.

A few days later, I heard back that they wanted to bring me onsite. I had a whole day of interviews. The questions were all interesting, practical problems to solve. No obscure algorithms or whiteboard coding were involved at all.
