Google Software Engineer III interview questions

4 rounds with different interviewers all mixed types. Interviewers were of wide seniority but were all on the project team. Questions did not rely on obscure theory but applying standard data structures and considering performance. It took 2 weeks after the interview to get an offer. The recruiter kept me informed throughout the process.

pretty strict with phone screen and then onsite interview process. The process is slow but makes sure only the good candidates get through. Not a lot of companies have such a long process. They care right from setting up the phone screen to everything. They also vet a lot of candidate from the resumes itself.
