One phone interview with recruiter and one face to face interview with hiring manager. The face to face interview was lengthy (1 hour) long. I passed the face to face interview and was asked to come back to give a presentation on a case study. I declined. I would have been more receptive had it not been for the fact the case study was company specific. I felt used in a sense to provide consultative analysis at no expense. Lastly, the interviewer asked "the ball question". I think this was amusing to the interviewer. It seems we googled the same topic. This type of question I would expect from a top Fortune 100 company. Lastly, I felt senior to the interviewer i.e. I would have done all the work and the manager would have taken all the credit.
