Google Software Engineer Internship interview questions

They took a few algorithm questions for me directly and asked my thoughts of the problem and the solutions' time complexity. Also they needed me to try to figure out some better algorithms whose time complexity is smaller than the former solution

Back to back phone interview. Each round is 45 mins. Average one question per round. Use Google Doc as a whiteboard to display code. Feedback was positive, the interviewers were very nice. They will help you to relax and perform better.
