Google Software Engineer(Internship) interview questions

There were about 4 phases. First was one was simple. There was no technical interview, it was only a description of my resume. Second one was online. They have a website like hackerrank which they used to filter candidates through questions. Third and Fourth were the normal 45 minute phone interviews. First one was a very helpful kind lady with an asian accent. Second interviewer was a little bit rude.

Round 1: Coding Challenge (Leetcode level: Easy) Round 2: 2 Phone Interviews (Leetcode level: Easy-Medium, but requires a lot of explanation of analysis.) Round3: 1 Phone Interview (Leet code level: Easy, but have to find multiple solution depending on different restriction, which makes it really difficult)
