Revolut Business Development Manager interview questions

Been approached via LinkedIn by a recruiter. Fast interview, had first call with talent manager, this lasted 30 min, then another call with the sales manager of another 30 and final call again with another sales manager and manager 1h Smooth process

Recruiter reached out, great 15 min chat. She sold the role I sold my soul. Was very handy with help for the interviews, nailed the first 2. Last one comes around and she reaches out telling me she's going to send me some info about what to brush up on ahead of the interview. We have 1 week before it, 4 days before I reach out asking what it's going to be about. No answer. 2 days before I send her another email but nothing. I have no idea who I am speaking to, no idea what the interview is about. 1 hour before the interview she sends me what the interview is going to be about, I obviously am not prepared. The interviewer was difficult to understand because of the accent. Manager for the role was camera off and muted in the call during the final interview. Just weird for a recruiter to be so involved up until the final stage.
