I was scheduled multiple times before I had an actual interview, they would cancel or ask to reschedule sometimes minutes before the start time. None of the people I interviewed with were people I actually ended up working with, so if you can just get through that part, the hiring team doesn't usually reflect the smaller team you work with. They use behavioral interview style, meaning they want tangible examples of what you've done in the past and will ask follow up questions to try and get specific details about the circumstances, outcome, and how you contributed. For leadership and clinical roles, they also use an assessment to determine fit for the role. Take it seriously, and in one sitting, they use those results to screen out a percentage of applicants, and you can't retake if for one year.
