Bank of America and J.P. Morgan are the two biggest balance-sheet banks in American investment banking, and students often treat them as interchangeable. They are not. J.P. Morgan is the largest investment bank in the world by revenue and posts perfect 5 out of 5 scores for prestige, compensation, training, and exits. Bank of America scores 4 out of 5 in each of those categories, pays slightly less, and works its analysts noticeably less hard, with a 3 out of 5 work-life balance score against JPM's 2.
The scale is enormous at both. JPM hires 500-600 analysts a year at a 3-4% acceptance rate; BofA hires 350-450 at 4-5%. Both run video screens, first rounds, and Superdays, and both use massive commercial banking relationships to win mandates.
The real question is not which bank is better on paper. JPM is. The question is whether that margin matters more to you than BofA's saner hours and its elite leveraged finance seat.
