I applied through their website and received a call from the Recruiter within 2 weeks. First phone screed was followed by a case interview which I found very easy. Then, I was called onsite at downtown SF from to interview with 4 heads of departments: Four interviews back-to-back went on for 4 hours: 11:00 AM to 3:00 PM. They should have offered lunch though. The interviews went well but the recruiter didn't call and it's been 1 month now. She didn't even reply to my emails. Very unprofessional!
