I had two phone interviews, and the questions were challenging. The interviewers were undecided about whether to call me on-site, so I had to take a third phone interview, which went well.

At the on-site interviews, there were four interviewers. They were very friendly and helpful, guiding me towards a solution. With two of them, I also had an open discussion about variations and expansion of the given system design/tech problem.

Design the Google search suggestion system. I proposed many solutions so as to show that I can approach the problem from different angles.
