The first interview involves mostly discussing your experience, etc. The second stage, to which you progress if you clear the first step, involves coding exercise. The coding exercise is your typical algorithms/data structures, which I personally believe are of little use in practical day-to-do work, unless your primary job is to design algorithms.

Recruiter call + phone screen + virtual onsite. Generally: nice group of people and engaging practical conversation + problem discussions. Some minor issues with structure or intent of the individual sessions. Recruiter followup was not conducted in the promised timeframe.
