Interview process started with multiple phone interviews (2). Each one was about 45 minutes and length, half of which was used for fit questions and half of which was used for case studies. After this, flew out to SF and had full day interview. Met with approximately 5 different consultants and each did fit questions and a case study. Never heard final response despite numerous phone calls and emails. Company seems ok, but no dedicated HR and unprofessional in the end.
