I had an initial phone screen with the recruiter, followed by a phone interview with the hiring manager, and finally an on-site interview with the hiring manager, director of product strategy, and a few others that took approximately 4.5 hours. It was not at the Orbitz HQ in Chicago, so parts of it were via Skype. This was not a problem at all.

The interview itself wasn't so much hard as it was an endurance test, talking to 7 people in 5 hours, not counting personnel. A list of interviewers was provided in advance, which was good for preparation, but for various legitimate reasons, the actual lineup of interviewers only had 3 of the original 7. It threw me off my game plan, but that's my bad. Doing it again, I would not be as focused on researching the individuals in my preparations, knowing that could change by the time of the interview.
