Ankura Senior Associate interview questions

I feel this is the worst interview experience I have ever had. Multiple phone interviews with the HR in Houston. He was the most unprofessional HR I have ever interacted with. In all calls he was late by at least 15 minutes, and constantly praised his professionalism by saying this is the only time that he has been late. The interview on site was not good either. They were disinterested, and cold. There were only two people working in that office and we had two separate 90 minutes long interviews which were identical in nature. They could have saved everybody's time by making them a joint interview. Finally they promised expense reimbursement which never happened. I don't really care but given the fact that they approached me through an employee referral (I never applied online) I think that is too cheap. The professional HR never got back to me and never responded to my expense request. Shameful.
