Every "why our bank" answer assumes a taxonomy nobody teaches you. Interviewers ask candidates to explain why this firm, existing answer keys tell candidates to tailor by firm type, and the Bank Guides in this app sort firms into tiers on the page, and then the vocabulary itself is left as an exercise for the reader.
So here it is, plainly, along with the part that actually matters: what changes for you, in the seat, depending on which kind of bank you end up in.
The tiers, quickly
Four labels cover most of the Street, and they are sorted by the breadth of what the firm does, not by how good it is.
- Bulge bracket. The largest global full-service banks. They advise on deals, but they also lend, underwrite equity and debt, and run sales and trading, across every region. Goldman Sachs, Morgan Stanley, JPMorgan, Bank of America, Citi, Barclays, UBS, Deutsche Bank.
- Elite boutique. Advisory-first firms with no meaningful balance sheet, competing for the same large mandates on the strength of advice and senior relationships alone. Evercore, Lazard, Moelis, Centerview, PJT Partners, Perella Weinberg.
- Middle market. Firms whose clients are smaller companies, meaning deals in the hundreds of millions rather than the tens of billions. Baird, Piper Sandler, Harris Williams, William Blair.
- Regional and sector boutiques. Smaller firms defined by a geography or a single industry. Often the best analyst experience nobody has heard of.
The lines are argued over, constantly. Jefferies and Houlihan Lokey both sit awkwardly across categories depending on who is drawing the map, Houlihan because its restructuring franchise is a market leader in a way its "middle market" label does not suggest. Rothschild is European in a way the American tiering handles badly. Treat the labels as rough shapes, not a ranking, and never argue about them in an interview.
The single most useful distinction is balance sheet. A bulge bracket can advise a client and lend them the money to do the deal; a boutique can only advise. That one fact explains most of the rest: why bulge brackets are bigger, why they cover every product, why they win mandates boutiques cannot, and why boutiques compete on senior attention instead.

Frequently asked
- What is a bulge bracket bank?
- The largest global full-service investment banks: Goldman Sachs, Morgan Stanley, JPMorgan, Bank of America, Citi, Barclays, UBS and Deutsche Bank are the names usually listed. They advise on deals but also lend, underwrite equity and debt, and run sales and trading, which is what makes them full-service rather than advisory-only.
- What is an elite boutique?
- An advisory-first firm with no meaningful balance sheet: Evercore, Lazard, Moelis, Centerview, PJT and Perella Weinberg are the names most often given. They compete for the same large mandates as bulge brackets on advice alone, rather than on the ability to also lend money, and they tend to run leaner deal teams.
- What is the difference between a bulge bracket and a boutique?
- Balance sheet and breadth. A bulge bracket can lend, underwrite and trade alongside advising, and covers every product and region. A boutique mostly sells advice. For an analyst that usually means broader exposure and larger, more specialised teams at a bulge bracket, and a narrower product focus with fewer people per deal at a boutique.
- Is a middle-market bank worse than a bulge bracket?
- No, it is a different job. Middle-market firms advise smaller companies, which usually means more deals, smaller teams, and more of each process visible to a junior. Prestige rankings favour the larger names, but the exposure a first-year actually gets is not ranked in the same order.
- Do you need to know bank types for an interview?
- Yes, implicitly. 'Why our bank' assumes you know what kind of bank you are sitting in, and an answer that would fit any firm on the Street is the most common way that question is failed. You do not need to recite tiers, you need to know which one you are in and why that shape of job suits you.
