As many people know, Google is definitely one of the best companies to work in the world. Interviewers are usually intelligent and vivid. A campus recruiter contacted me via email, and made a schedule to have a talk over the phone. He checked my background and interests and explained the general interview process in Google. Here, you may realize later that it is also a part of evaluation process. He or she tries to see your enthusiasm for digging into new technologies in Google and how you can fit yourself into Google. A week later, I've got a technical interview with an engineer. We spent a half of scheduled interview time (20 min) to introduce my experiences and Q/A about some skills and notion. Then, he asked a simple coding question and requested a solution for a scalability problem.
