This was a fairly straightforward process. The recruiter contacted me based on a recommendation from a contact within the hospital and set up an initial phone screen - typical questions during this interview. After the phone screen, there was an Excel and Business Case that required about an hour each. They weren't overly difficult but it would be wise to brush up on these two topics so as to be prepared.
I was asked to come to the St. Louis office, where I had four interviews (some with multiple people). Again, the questions were fairly standard and everyone was quite cordial. They will want to see some of your past work and you should certainly be prepared to answer some hypothetical business questions.
After the on-site, there was a final phone interview with a senior leader at the company - this was more of a get-to-know-you because, by that point, they have an idea of whether they like you or not.
Overall, a pleasant experience. The only negative aspect was the time commitment needed - the process covered several months, and each interview was roughly an hour or more in length.
