3 interviews- 1. culture fit 2. analytical 3. visit headquarters...overall process took about a month and was very easy. Make sure to read a few articles about BK before heading into the culture and headquarter interview. Also look at a few examples of analytical questions before doing the analytical interview.
I attended an open interview that was advertised on craigslist, was granted the job, and before I started even filled out hiring paperwork, the manager who held the interview was gone, and new management came in and asked to interview me again. I do not know if the old manager was fired, quit, or what really happened.
