Very simple interview process. I applied and got emailed about an interview like a day later. Had my interview the following week. They offered me a job on the spot. I applied for part time, but they offered me full time

3 rounds of interviews. 1st being a behavioral secondary being practical questions and overall knowledge for position. lastly being conformation of availability and offer. The overall tone for the first interview was relaxed. Second being intense and structured. Last being relaxed.
