6 Interviews including the initial manager screen. Took almost six week. Interviews included several technical interview with multiple engineers in attendance. One included a difficult coding problem that on a scale of 1 to 9 in difficulty, felt like a 8 or 9. Process included a coding challenge take home assignment with a challenging but not overwhelming problem that I put ~ 24 working hours into. In addition, I was required to provide proof of prior salary by handing over pay stubs. This was very unusual and I have never in the past been asked for this.

First, there is a behavioral interview with a hiring manager. Next, two technical interviews with pseudo coding. Finally, one system design. The interview is conversational. Emphasis is placed on your reasoning and not necessarily compilable code.
