Google Software Engineer Internship interview questions

Applied online in September. Received a snapshot test + questionnaire later that day. Heard back within a week, but didn't receive an interview request for three weeks. After another 3 weeks, I was told they couldn't schedule the interview during any of my dates and it got moved back to the end of November. Apart from audio quality issues, the interview went well and the 2 interviewers were very polite and helpful. Roughly one month later, my recruiter requested I complete another interview. This one was scheduled much faster and seemed significantly harder than the first set of interviews. After 2 weeks I was told I had passed the hiring committee and was invited to the host matching stage. I received a request for a host interview in mid February (about 3 weeks after I started host matching) and received an offer the following Monday.
