I applied online and got a call from HR for a screening interview. I then interviewed with a regional VP a few days later. I visited one of the campuses shortly afterwards to have a first hand look at their operations. A week later, I was invited to the final interview along with about 10 others in Chicago.
I had 5 interviews with some being one on one and others being two on one. The questions were insightful and designed to truly identify the best candidates. There is a strong need to prove your commitment to the company and program on a long term basis (otherwise you will not get the offer).
Got the final decision in less than a week.
