Arity Compliance Analyst interview questions

I had a short call with the HR representative. He was very encouraging. I then met with the hiring manager and members of the team. Everyone was nice and I felt positive coming out of the interviews. I then received no follow up whatsoever. I’ve received rejection calls before. It’s not the best but it’s part of the process. At least you know and can move on. But to just go silent after a candidate has spent several hours preparing and being in interviews is very unprofessional in my opinion.
