It's very straightforward. I got a call and, being in Boston, had one Google Hangout interview. After that, I had five onsite interviews back to back. The following were the rounds:

1. Programming: General programming questions like ArrayList vs. LinkedList, etc. Pretty trivial.
2. Programming (Harder): Largest island, dynamic programming a bit.

Then, I had a great lunch with some of the employees! I had quite a good time, honestly.

1. Cultural Fit: Normal cultural fit questions, nothing specific.
2. System Design: Design a "like" button. I started with unnecessary complexities without analyzing the problem. It was a much more simplistic, solutions-based problem which I thought from a scalability perspective, etc. This is where I flunked, I guess.
3. Case Study: System outage diagram. I was told to investigate.

I was able to get through all the rounds easily. Only the system design round was unexpectedly bad.
