Victor BDR Manager interview questions

6 interviews over 3 months, massively drawn out. First I met with a founder, then head of sales US, then an account manager, then another founder, then an external advisor, then head of marketing (which was meant to be an informal teams meeting) the call turned into another interview as another founder joined the call out of nowhere, grilled me and completely caught me of guard. After weeks of chasing, I eventually recieved a rejection email from a recruiter I had never spoken to. Rejection is fine, how they went about it isn’t.
