Bankable Implementation Manager interview questions

I was called back very quickly after sending my CV over, and the first person I talked to was quite nice. I was then scheduled for a call with the hiring manager. It was an interview over Zoom and I had my camera on but he didn’t bother turning his on. The whole interview was pretty painful, and was mostly about asking me if I knew some very specific acronyms from forms I had used in a job two years prior, and I don’t feel like I did very well. After that no one bothered to call or email to say the process would end there, which is pretty rude. But this interview did not make me feel like I wanted to join the company.
