Google Software Engineering interview questions

The whole interview process takes 2 to 2.5 months to complete. Google interviews for software developers consist of 5 to 7 interviews in total. This includes an initial phone screen with a Google recruiter, followed by 4 to 6 on-site interviews with different Google employees

You will receive an online 1-hour quick interview, then the recruiter will contact you to make appointments for 2 phone interview. I failed here so I did not get to move on to the next round. Overall, the questions are interesting that requires good understanding of data structure and algorithm.
