Presentation required on a subject of their choosing. Complete waste of time because they interview you knowing that they are going to hire an internal client. The interviewer knew less about the subject matter than I did. He seemed very uninterested and rushed through the interview. Within 30 minutes they called to say that they went with an internal client. Totally insensitive. Just hire the internal client or at least don't waste the candidates time by requiring a presentation that requires a week of research.
