Microsoft Project Manager interview questions

I had 2 days of panel interviews. First day was a virtual interview (over Skype) with 2 managers. On the 2nd day was face-to-face, again with 2 managers. On the 1st interview day the questions were specific to my actual experience. The 2nd day wasn't good--I was quizzed on academic questions as items contained in the PMBOK. I believe these were unnecessary and intended only to confuse and intimidate the candidate.
