Round 1 | Online Written Application - includes resume, cover letter, and a few written essays. Very standard.
Round 2 | Video Interview - you get 1 minute to prepare a video taped response to the given question. A lot of people think this is uncomfortable, which is understandable. However, the whole process takes about 20 minutes and is fairly simple.
Round 3 | Group Interview at 30 Rock - the day is split into different segments. When I interviewed, there was a group interview, a small group discussion, a personal interview, and a 2 minute timed speech. Although the day is stressful, the Page supervisors do a great job at making the whole experience fun and enjoyable for everyone there. BONUS - snacks, drinks, and breaks are provided!
