It was a Job Fair for new graduates. Everyone shows up and visits different tables to do mass interviews with all the local hospitals for the residency program. If the interviewer like you, they will then invite you for a more formal interview at the actual hospital of choice.

My interview took place over the phone, and 2 interviews total. In a separate phone call prior to interviewing with the director, Human Resources personnel went over all the details of the job and was he was very helpful.
