J.P. Morgan Associate - Quantitative Research interview questions

I interviewed for the position of Quantitative Research Associate for three different desks at JPM. The HR/recruiting teams for each of these groups did not communicate well with themselves internally. In total I had 6 interviews with the wholesale credit team, 2 with their RAAS group, and 1 with their rates desk. Eventually, I received an offer from their wholesale credit team for what I believed was a below market offer. When I attempted to negotiate, they came back saying this was the most they can do, and I walked away.
