I received an email from one of Google's recruiters offering me the possibility of entering the hiring process for a Software Engineer position.

After a relatively simple phone interview, which included a programming problem (no code was necessary, just a solution), I was invited for an on-site interview.

My agenda there consisted of five different interviews, all with Google engineers. In each of them, I was asked about the fundamentals of Computer Science and was also given a programming problem.

For most of these, you had to provide code (C was always an option) and analyze the computational complexity of the solution.

I left the offices thinking I could have done better. Perhaps I was just too nervous or too in need of the job.

Differences between two programming languages appearing on your CV (the interviewer chooses which ones).
