Moz Senior Project Manager interview questions

Applied online. Received a request to schedule 30 minute phone interview. 2 weeks later got a request to schedule in-person interview for half day. Met department head via google talk which went fine. Then had three two people interviews at 45 minute each (included other PM's, Dev and Dev managers). All three pairs ran out of questions first 15 minutes. I ended up asking the next 30 minutes everything about the product and company. The interviewers were straight forward, telling me "as you can see this is our first time interviewing a pm". Last I met the hiring manager who did not have a single question to ask. By that time I ran out of any possible questions that I could ask the hiring manager so the meeting was only 15 minute short. Got an email with denial 1 week later. They have nice benefits and a cool office. Too bad they didnt ask any real Scrum/PM questions. I really doubt they could make a correct decision without asking proper questions.
