Google

The interviewer let me do the five programming questions. The first one was easy. The others were all hard for me. He also asked me other ordinary questions, like, "Introduce yourself" and "Why did you choose Google?"

There were 1 non-technical and 3 coding rounds, followed by final review rounds. I cleared up to the 4th round and I guess I missed the last one on maps. The non-technical round was as usual and normal.

The interview process is very extensive. Several technical interviewers take turns asking very difficult math and logic questions. The applicant is expected to solve the problems on the whiteboard while the interviewer watches and asks questions.
