Google Intern interview questions

2 telephonic rounds of 45 minutes each. Though second one went for more than 1 hour. Live coding on Google doc in both the rounds. First round was very easy and a simple question of Strings was asked to check basic programming skills. In second round, there were 3 questions asked from dp and basic ad-hoc.

Initially it was 2 technical 45 minute phone interviews. Need to code on a shared google doc. Then they called for an additional one. So 3 interviews in total. It took around a 3 weeks. I wouldn't call it a difficult interview. The questions were very straightforward. No googliness or puzzles. Basic data structures and algorithm, especially trees. 2 of my rounds were on trees. If you are done with CTCI, you should be able to ease it. Get your data structures strong, really strong . Also, get comfortable coding. This is very vital, as interview preps can stress you out and you can blank out even on the basics. So practice a lot.
