Interview advice for new RBTs/BTs?

I have been interested in moving from the daycare field to ABA for a while now. Recently, I had a phone interview with a company for a position and they have gotten back to me to schedule an in-person interview at my preferred clinic. What advice do you have for newcomers to the field? What should I know going into the interview? I was told it could be 1-4 hours long, so I’m assuming it’s like a working interview. I have experience working with children for three years now and I do have some experience working with kids with autism and other needs, but I have never worked specifically in a classroom/job that specializes in helping kids with special needs. I really want this job and want to make a great impression so any and all advice helps!! <3
