I went to a recruitment event at my school and then applied online. I was contacted in about a week for a phone interview. The phone interview involved coding on an online platform. Then, I was contacted a few days later to arrange an in-person interview. They paid for me to visit their New York office for the interviews. The HR person was very helpful and well-organized. I had four in-person interviews, all on the same day, all with two interviewers. Each interview asked one programming problem, which I solved on the whiteboard. There was also the option to solve them on a computer. The interviewers tended to observe quietly, and didn't give many hints, preferring for me to work through it when I got stuck. They were all very intelligent. I actually found it pretty fun, since the questions were interesting. They made me an offer a few days later.
