Google Project Manager interview questions

Had a first phone interview screening. Was easy very simple where Google requiter explained the position and a what will be next. Next was video call interview (via hangouts) with Senior Project Manager. It went very well (I thought so), answered all the questions and gave a fairly amount of examples from my day to day work and from my own experience. Got rejected few days after and the feed back was that in one of the scenarios they presented to me I didn't ask enough questions and made my own assumptions. If you ask me... I wouldn't fail myself just because of that. I mean, how harsh can you be? While got really tons of experience... oh well. Good side - Google reciter was amazing!! Very easy going and was very very pleasant process.
