Google Software Engineer Internship interview questions

Applied online, got rejected, talked to the recruiter again at a hackathon, got 2 on campus interviews, followed by 1 additional phone interview. Waited in project matching for 4 weeks.

I first filled out an online application with a resume, and was later contacted with a coding challenge, which consisted of two questions and took 90 minutes. After passing the coding challenge, I moved on to phone interviews, of which I had two about a week after scheduling, and then was later asked to complete a third interview. These interviews were primarily technical, held over the phone, and the programming was done in a Google doc. The phone quality was somewhat poor, and I had a difficult time understanding some of the interviewers, but they were all very polite. The recruiters were also very helpful and quick to respond to emails.
