I had one interview and I got the job on the spot. I found out about the job through a friend who was also recently hired in the same week. I dressed in business formal attire, and I met with both the hiring manager and the manager who would be directly overseeing my department in the same day. Overall, it was a very relaxed interview. The company seems short-staffed as they hired me on the spot and asked me to start working within a week of the interview itself.
