The process took about 3 weeks from application to final rounds. I had a small talk/technical screen with the recruiter, an interview with the hiring manager, a take-home assignment that took 1 week, and then final round interviews with three senior engineers from the team I was interviewing for. The take-home assignment was moderately difficult and involved a systems programming challenge. The final round interviews consisted of a mix of questions regarding my assignment (how would you do "X" better, etc.) and standard miscellaneous technical questions. I left the interviews feeling quite turned off by the company because of my interview with one of the engineers; they interrupted me several times while I was answering a question.
