A recruiter reached out a number of times to see if there was mutual interest. When I finally responded that I was interested, I was given an over-the-phone technical interview.

The interview was broken down into three parts:

• Implement a solution for some arbitrary problem.
• Come up with test cases for it.
• List the smoke tests for some Google product.

After that, the on-site interview consisted of five back-to-back technical interviews. There were no real drink or snack breaks, except for a brief 30-minute lunch. The interviewers were rather impersonal, so the prospect of working with some of them didn't excite me.
