What investment bankers actually do
Advisory, financing, and why companies pay for either.
- Banks sell advice (M&A) and access to capital (ECM/DCM).
- Fees scale with deal size, so valuation is never academic.
- Junior work centers on modeling, materials, and research.
Two products
An investment bank sells two things. Advice on buying or selling a company (M&A), and access to money (equity and debt capital markets).
In M&A, the bank runs the process: it finds buyers or targets, builds the valuation, and negotiates. In capital markets, the bank helps a company raise cash by issuing shares or borrowing.
Why anyone pays for it
Deals are rare events for a company and daily events for a bank. Clients pay for pattern recognition, for a rolodex of buyers, and for someone to stand between them and a hostile counterparty.
Fees are usually a percentage of deal value, which is why bankers care so much about the number a deal prints at.
The analyst's day
Most junior work is three things: building models in Excel, building pitch materials in PowerPoint, and doing research on companies and comparable transactions.
Interviews test the first one hardest, because a model is where every accounting and valuation idea shows up at once.
Apply the lesson to explain advisory, financing, and why companies pay for either. Start with the answer, show the bridge, and sanity-check the direction before stopping.

A company wants to sell itself to a larger competitor. Which group leads?
A profitable company needs $500M of cash and does not want to dilute shareholders. What does it most likely do?
- Banks sell advice (M&A) and access to capital (ECM/DCM).
- Fees scale with deal size, so valuation is never academic.
- Junior work centers on modeling, materials, and research.
