3 rounds and a week long. A coding challenge, you need to solve remotely. After that they call you in for a F2F or phone interview, depending on your location. When you come in, the questions were mostly about the projects you have earlier worked on. Also they touch some alogirthms and data structure problems. Mostly pretty basic stuff. And then if it goes well, you will 'meet' a number of senior people like Directors, VP etc.

I applied through consultancy. If you go through cracking the programming interview book you can clear all the rounds and get through it. They mostly covered the basic data structures and some average coding problems. It is more like a thoughtworks interview but interviewers are a bit more friendly
