Google Software Engineer Internship interview questions

It has 3 phases of selection, first 2 rounds were technical rounds and the last one was the HR round. I firstly cleared the round 1 of technical round. It was having 2 questions 1 medium and second Medium-Hard type. I amanged to solve and code both of the questions in 45 mins. Next, I got selected for round 2. I gave the round 2 but it didnt go well. So was not selected for round 3. Overall, a greart experience was having to be filled in interviews at Google.
