I sent my resume to Google without reviewing the site or Google's job requirements. I was called for a first-level phone screening, which was easy.

The recruiter was very nice and got back to me quickly. We then moved on to the first phone screening.

I had been non-hands-on for a few months, so the phone screening was a bit more challenging than it should have been. The interviewer wanted in-depth answers, like how the struct and bits were aligned.

Note: Review your C and computer science topics, including algorithms and Unix system engineering.

I strongly suggest reviewing 'Design of the Unix Operating System' before going into this interview.
