IT Audit Senior Associate offer negotiation tips

Currently towards end of interviewing process. I’m looking for any insights into what I can negotiate or should demand for with the offer. 4 YoE, PwC ME.

Also, kinda curious. The interviewer asked my experience in years, when I said 4+ he mentioned we only have senior associate position and manager, there’s no assistant manager. Does that imply I’m qualified for more than senior associate? I’m thinking of using that as one of the bargaining chips.

Any insight would be appreciated.
