First round easy, but the woman that does all the interviews is stern. No technical questions, but you probably won't walk away from it beaming either. Be prepared with basic stuff (tell me about yourself, tell me about a disagreement, tell me about a challenge). It will not be conversational or friendly. Will stick to strict interview format. I found this odd, since even interviewing at Bain, McKinsey, etc., interviewers were always very friendly.
