Google New Grad Software Engineer interview questions

I had a Google chat interview with video on and then a google doc to code in. My interviewer had been working at google for 10 years, which I really appreciated since he knew what he was doing and had clearly interviewed people before. He was a great interviewer! We talked things through in the interview and got along great. He wasn't a know-it-all like I've experienced in a lot of tech interviews. If I answered it and it was slightly off he would simply tell me what might happen and why it wouldn't be ideal.
