I had an initial phone call to discuss my interests.

Then, a new recruiter emailed me to schedule a technical interview.

Afterwards, yet another technical recruiter called me by phone to conduct a phone interview over Google Docs.

It was a good experience. The questions were hard, but not overwhelmingly so. My questions literally came from the book "Programming Pearls."

So, after you brush up on your algorithms, go read "Programming Pearls."

In the end, Google did not offer me a position. It was a very interesting experience that taught me a lot.
