Interviewed Dec 2011 (took 2 weeks)

1 phone call from recruiter and 45 minute technical interview. The position did not match my background or skills at all the technical interview was confused as to why the recruiter set me up for his team. He was also condescending and said everyone in his team had 10+ years experience and that he does "very intense things" ?!

study linked lists. The other questions were algorithm "how would you solve this".

Interviewed Jun 2011 in New York, NY (took a day)

They provided a list of items to study. I had 2 1 hour whiteboard interviews with two engineers. I described my resume and solved some algorithm on the whiteboard. The first interviewer was the Manager and he was more intersted in how I would fit with the team and my interest in the different projects. His technical questions were few but he did ask how to test some functions. The other guy was a SDET and his questions were all technical and I spent most of the interview writing code.

Reason for Declining

They wanted someone to spend long hours performing Unit Tests and such like on various software designs. I'm a bit more outgoing and wanted to stretch my capabilities with actually writing real design code

Interviewed Apr 2010 (took a day)

I had a friend send in a referal and my resume for a Software Engineer position. A few days later, I got a call from a recruiter where we discussed either doing a Software Engineer interview or a Test Engineer interview since I have those skills on my resume. My algorithms knowledge is rusty from age and Google is very algorithm-heavy in their interviews so I went with the TE interview. A few days after that, I had a call with a engineer from a testing group. He asked me a few questions about "How would you test X", I had to write a small function in a shared Google Docs page and we talked about the job. I didn't feel I did very well since my testing experience isn't the large-scale stuff they need. Sure enough in a few days the recruiter told me "they didn't have any positions that would fit my skills". It was a pleasant call though, and I'm glad to have the experience interviewing with Google.
