I used to apply for an internship at Google but got no response. One day, a recruiter found me and asked me to consider their software engineering position. Then, they arranged a technical interview. I worked on a Google Doc. I had other commitments on the previously scheduled date, so the recruiter rescheduled the interview for me. It was about 45 minutes. The questions were very easy.
