Google Software Developer Internship interview questions

The process is great. I spent a lot of time discussing with the problems. However my ability is not enough so finally I failed... (Fill up to 30 fill fill)

The interview lasted for 90 min. Two interviews 45 min each. None of my interviewers spent more than 20 seconds talking about my background. Your approach to a algorithm tech problem is paramount. Language of the questions is very contrived, but if you can break them down in simple terms, they are pretty standard (easy to medium on leetcode).
