Interviewed Feb 2010 in Mountain View, CA (took 3 weeks)

Interviewers were smart people. Questions were good. The recruiter gave a call first to find out about my technical skill set, background and later set up time for a phone interview.
First phone interview was good, questions asked were a coding question, testing question.
Got feedback from recruiter, saying that they needed to do another phone interview
Second phone interview went well too...but no offer.

Interviewed Apr 2010 in Mountain View, CA (took 2 days)

Was first contacted by the recruiter for a phone interview. The phone interview lasted about 30 minutes. A document was shared over Google docs where I had to answer a programming question and type the answer in the doc so the interviewer can see my code. Once you pass that stage, the next round of interview was on campus interviews with 4 different QA engineers with a lunch break in between. The questions were not particularly hard but apparently I didn't do well enough to get the job. 3 out of the 4 QA engineers asked about mostly programming questions while the other asked mostly about QA questions. Not a lot of data structure questions, no linked list or anything that. I did have to show how to do merge sort. The interviewers were all very nice and knowledgeable.

Interviewed May 2007 in Mountain View, CA (took 2 days)

I heard that the interview process was tough to get into Google. Who knew that simply scheduling one would be just as daunting. For a basic phone screen, I was rescheduled 3x, and usually at the last minute. In fact for one of them, the interviewer forgot, and I was rescheduled.

The phone screen wasn't too hard, but they wanted to make sure that interviewers had a solid grasp of web technology and terms like URL (what it stands for, how it works), DNS, what HTTP stood for. While good questions, they had nothing to do w/ testing techniques.
