There was an initial phone screening, 2-3 phone interviews, and final google hangouts video call. I averaged a little more 1 phone interview per month for about 4 months. None of the technical algorithms are particularly hard if you can make it through a CS degree, but implementation can be kind of a pain if you don't practice coding questions.

Contacted by the recruiter. She set up a call with 2 back-to-back google hangout call with the engineers. I thought I did horribly as I wasn't able to write up the code in the given time; I was only able to identify that its a BFS problem and what data structure will be most efficient. Somehow I made it to the next round and had another google hangout call with a different engineer. This time I was able to solve the problem and improve it. I got rejected after few days. The whole process until I got rejected took a month.
