Priority Pass interview questions

Received first call for screening, was transferred to who would be the manager, was interviewed/screened some more, was transferred back to HR to schedule in-person interview. Went in for an interview and was called back the next few days with an offer.

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.
