Google Software Engineer (Tools and Infrastructure) interview questions

First I got an email from the recruiter. They scheduled a phone interview with me. After the phone interview there's an online technical interview where you solve a few problems. Once you pass that, you get an on-site interview. The interviewers on-site start off with a basic question and then asks some follow-up questions which are harder.

I applied online during the first week of June and got a call a week later. I had two phone interviews, both on Google Docs . The first phone consisted of 2 questions - I managed to do both questions but felt I was slow. The HR called me up to schedule another phone since they were not sure about me. In the second they asked me few questions on Resume and 1 question, I managed to do the question but felt I took a lot of hints, don't know exactly what was the case. But overall it was a good learning experience and I feel a little more practice I can crack it down next time.
