BDO Sr. Associate interview questions

A short phone screening call with an HR rep, a one hour long video interview with a team manager, followed by an offer and negotiations entirely over email. In each communication step, they kept lowering the salary range and ultimately offered nearly $20K below the initial salary range that had been explicitly confirmed by the HR rep. The position was also listed as hybrid and in the interviews they said they allow a few days of remote work each week, yet in their offer they said no remote work. Upon negotiations, they refused any counteroffers and did not even bother to have a conversation about it, only sent a dismissive 2 sentence email. It was the most bizarre and unprofessional negotiations process I have ever experienced. Seems like they intentionally try to wear down and pressure candidates into bad offers through drawn out false advertising. As such, I declined the job offer not solely because of the salary but because of the lack of transparency, management skills and basic respect displayed by the management and hiring team.
