I applied through a recruiter.
I was contacted within one week of applying, the interview process consisted of two interviews with senior Managing Director's.
The questions asked were more directly applicable to wealth management than they were behavioral. As an intern, they don't expect you to have a large skill set pertaining to Wealth Management and so they focused on what I was looking for in BNY Mellon and skills I had pertaining to Excel, Powerpoint and team work.
