A representative from Google came to our school's ACM club, and that is when I gave my resume to Google. About four months later, seemingly out of the blue, I got a call from a recruiter asking if I was interested in interviewing with them. We set up another call to get to know me better. During the call, we talked about the technical interviews that would be coming and what to expect.

After a fairly standard question (which took about 7 minutes to code up), the interviewer went very in-depth with how I would test the code to ensure it worked.
