Professional Fighters League interview questions

Very unprofessional process. The job title changed in the middle of the interview process without them notifying me. I had to find out via LinkedIn. In the first interview, the hiring manager mentioned the previous person in this role "sucked at his job." In the final interview with the CRO, he straight up asked me what my salary was in my current role, which is illegal.

One call, 20 minutes. Asked combination of questions about myself and about my interest in the company. Was not very difficult. Held room for me to ask questions. Very relaxed and laid back.
