I asked some version of 'why us' in most interviews I ran and I can tell you the base rate: roughly four answers in five were the bank's own website read back to me. Global platform. Excellence. Culture of collaboration. Putting clients first. The candidates were not lazy; they had researched. They had simply researched the one source engineered to say nothing distinctive, because a bank's website is written to be agreed with, not to be repeated.
The test every answer must pass
One question exposes the whole category: could this answer be given, unchanged, to the bank across the street? If yes, it is not an answer to 'why us'; it is an answer to 'why banking' and I already asked that one, which has its own article. The why-this-bank answer must be non-transferable. Everything below is just machinery for making it so.
The three-layer structure
- 1 · A platform fact that actually differentiates. Something true of this bank and false of its neighbours: a franchise strength in a sector, a distinctive mix of deal types, a position in a market you care about. League tables, read properly, are the richest source here and the league tables article shows how to read them as a candidate rather than as a journalist.
- 2 · A deal or theme connection. One transaction or sector theme the bank touched that intersects with your genuine interest, held at the level of 'I followed this and here is why it matters', not recited tombstone detail. Your deal sheet, built the way the deal sheet article on this site describes, should already contain one deal per target bank for exactly this moment.
- 3 · A people proof. Evidence you tested the platform against humans: 'three conversations with analysts in your Paris office' is worth more than any adjective, because it is verifiable, effortful and specific. This is also where a networking season quietly converts into interview material.
A worked template
Template · a why-this-bank answer that survives
Three reasons and they are specific to you. First, the franchise: your team runs one of the strongest mid-cap software practices in Europe and that is the sector my research and coursework have actually focused on. Second, the model: you staff lean teams on full processes and I would rather learn every workstream of a mid-sized deal than one slice of a mega-deal; that preference is why you over the larger platforms I am also interviewing with. Third, the people: I have had three conversations with your analysts and an associate since the spring and the way they described junior responsibility here matched what I am looking for closely enough that this became my first choice.
Notice the mechanics: a franchise claim that can be checked, a stated preference that explains the choice rather than flattering it, named conversations as evidence and an implicit acknowledgement that other processes exist, which reads as confidence rather than disloyalty. Ninety seconds, no superlatives, nothing transferable.
The follow-up is where it is really scored
Whatever you claim, expect one probe: which deal specifically, why that sector, who did you speak to and what did they say. This is why borrowed answers collapse; they are one layer deep by construction. The rule from the why-banking article applies with double force here: an answer only counts if it survives its follow-ups, so build each layer from things you can discuss for two further minutes without preparation.
The boutique variant
At a 20-person M&A boutique, why-this-bank is not a question in the interview; it effectively is the interview, because the honest answer at a boutique involves choosing their model on purpose: earlier responsibility, thinner safety nets, partner exposure, a narrower franchise you must actually want. The platforms article maps those trade-offs and interviewers at smaller firms can hear within a minute whether you understood them or applied everywhere and hoped. Make the choice legible and you are ahead of most of the pile before the technicals start.
If you want your three layers stress-tested with the follow-ups a real interviewer would run, that is a standard segment of the IBD Recruiting Review.
FAQ
How do I answer why this bank in an interview?
With three layers: a platform fact that differentiates, a deal or theme you genuinely followed and a people proof from real conversations. The test: the answer must not transfer to the bank across the street.
What should I not say when asked why this bank?
Anything from the website: global platform, culture, excellence. Recited marketing is the answer four in five candidates give and it answers why banking, not why us.
How do I prepare the why-this-bank answer for a boutique?
Choose their model on purpose and say so: earlier responsibility, thinner safety nets, partner exposure, a narrower franchise you actually want. At a boutique this answer effectively is the interview.
