Google Software Engineer - Internship interview questions

Applied online. Did google foobar. Called me and asked me questions. That's about it. Send me another coding challenge. Then they phone screened me. Questions were reasonably difficult. Shouldn't be that hard if you prepare throughly though.

My friend referred me the position. It takes one week to begin the interview process. Due to some school work, I deferred the interview to one and a half months later. The recruiter is very friendly.
