Google Software Engineering interview questions

I applied online through their general link for internship applications. Was surprised to hear back just a few days later from a recruiting coordinator, who asked me to choose 3 time slots for phone interviews. The interviews ended up being about 3 weeks after our initial contact. The phone interviews were rather relaxed, the interviewers were very nice. I definitely over studied, I was memorizing complicated graph algorithms and other high-level topics and the interview questions ended up being much simpler than I expected. The three interviews were all back to back with 15 minute breaks in between, and I think I did pretty well overall. There was one programming problem (out of 6 total) I was not able to answer fully, and I'm going to be kicking myself about it for some time. I have not heard back from them yet (interview was yesterday), so no word on offer/ no offer.
