The first step was a timed online test to write a certain data structure, not a very typical one. Not a rocket science, but it required some careful testing. Looks like I did OK. Then I had a phone interview where I was asked to implement a certain algorithm. This part was far from perfect, it felts like the interviewer was out of time and put me on hold a couple of times asking to email him when I have an updated solution - which was very different from the usual process where you first implement a basic solution, and then asked to accommodate more specific requirements. If you are preparing for an interview there, you might want to warm up by implementing some textbook or STL data structures and algorithms from scratch.
