Overall a very positive experience! The interviews felt more like conversations and everybody I spoke with was really nice and made a relaxed atmosphere. First round was a typical interview with a recruiter asking questions about my past experience and motivations. Second round was with a department lead who asked more prying questions into my mentality, goals and working style. This was followed by a technical task which was pretty straightforward although it did have a couple of caveats. Nevertheless, it doesn't take more than 1 evening to do. Final round was a technical interview with the head of engineering and another developer. I was asked a bunch of theoretical questions and then was given a coding exercise to complete at the end.
