1 phone screening plus 3 rounds of interviews, with each consisting of approximately half behavioral and half case study. From the time of the phone screening the process took approximately 6 weeks. I was told I performed well on the first 2 interview rounds, however was given no specific feedback as to what in particular I did well or could have done better. I was told "do what you did before again" in the final partner interview. After the partner interview I was not contacted for a weeks and followed up via email to be told I was not successful. I put negative experience because I believe the best practice is to contact a candidate and provide some type of feedback on the hiring process after 4 rounds of interviews and such an investment. After asking for feedback none was available and it wasn't clear what part of the interview was attributable to the outcome. Other firms I interviewed with were much better and providing feedback and updates - based on my experience in the interview process I'm not disappointment I did not go to work there.
