Google Software Engineer Internship interview questions

There were two technical interviews. I was asked to solve a programming problem in each of the interviews. However, there was not much interaction with the interviewer. So I was not able to tell whether my solution is good or bad.

Coding assessment through HackerEarth. I was given 60 minutes for 2 hard questions. Only passed half of test cases for both problems due to time limit exceeds. Didn't get any update after then.
