eBay Sr. Project Manager interview questions

The recruiter called me to have a chat and fixed a Skype call with the hiring manager on a particular date and time. A day before the scheduled Skype call, I was called by another recruiter to fix a face-to-face interview the following week. I waited for the Skype call as scheduled, but got no call at all. There were frantic emails from another recruiter asking if I am on call and things like that. After that nothing happened at all. I proceeded to the face to face interview the following week. That did happen as scheduled without any reference to why the Skype call never happened. The interviewer's only main questions were around Scrum and arguing why the Scrum that eBay followed was "perfect" (I am an Agile practitioner for several years and hence my answers could not have been lame). It could not have got any more shallower than that for an interview for something as strategic as Product Manager.
