Google Engineer interview questions

I got a call to schedule a initial phone interview. It was scheduled in a week, but the questions they asked me was somewhat unanswerable under my knowledge. So I failed. I want them to go little easy on the interview and try to get to know the candidate a bit more than just asking the whole bunch of difficult questions. I don't like that!!!

Google contacted me, they had my resume from an old interview many years ago. After a few email exchanges about available positions, a phone screen was arranged. During the phone screen they asked technical questions to gauge my skills. It looks like I did well because after that I was invited for an on-site interview. If I remember correctly, first I was interviewed by 2-3 people (like a panel interview) and one of them was dialing in from a different location. They asked mostly general and architecture questions. After that I had two one on one interviews. The first one was with a software engineer who was very polite and asked me about general programming stuff. The second one was with a network / sysadmin but he was rather rude, and flatly refused to answer any of my questions during the course of the interview. It was like, I had to answer questions only, and not ask anything. I felt very uncomfortable and disappointed.
