HR phone interview was the first step, which lasted approximately 45 minutes. After that, there was a second phone interview with the hiring manager, which lasted approximately an hour. If you succeeded past those 2 screenings, they either flew you in or invited you to a face-to-face interview at the NY HQ office. This took about 3 to 4 hours depending on how many people you meet. Usually you meet about 4 including HR. It is pretty intense. The culture there is very corporate but people are very smart. It is a great place to kick start your career.
