I went through 2 rounds. The first was the behavioral, and the recruiter was about 5 minutes late to call. That went well otherwise. The second round was a take home 3 hour case study. I asked the recruiter if I needed any specific tools/programming languages installed (just got a new computer) and they said no. I installed them anyway, lo and behold the case study was definitely meant to be completed with some sort of programming language. I used Python and got stuck on some bugs and didn't get as far as I had wished. This was also my first ever case study assignment. I was not asked back for another round.
