Expect them to cater to you, including the CEOs and MDs.
Show up on time and dress professionally. Smile. Be cordial. It’s not a residency interview. They basically want to know if you have a pulse and look for obvious red flags.
In a sense, you are the one interviewing them and not the other way around. They know that you have options. You don’t need any particular job because it will always be easier for you to find a job than it is for them to find a physician. We are few and far in between. Own this.
Good luck!
