Equity Research interview preparation
Sell side and buy side. Every question is either traced to a named firm from a public candidate report, or tagged at desk level when we could not trace it. Answers lead with the point, then the mechanism, then the limitation.

Say this
Answer the substance, do not defend the position. Say what evidence supports the cost assumption, quantify what happens if you are wrong, and state at what point you would exit.
Then walk it
- First, give the evidence behind the assumption, specifically. 'Management guided to it' is weak. 'The input contract repriced in Q2 and the run-rate is already visible in the last two quarters of gross margin' is strong.
- Then quantify the downside. 'If costs stay flat, EPS is 15 percent below my number and the stock is worth 38 rather than 55, so I lose about 5 percent from here.' That shows you have modelled the bear case, not just the bull.
- Then the asymmetry: if the downside is 5 percent and the upside is 35, the position still makes sense even at a 50 percent probability. That is the real defence.
- Then the monitoring point: which disclosure tells you early that you are wrong, and by when you would expect to see it.
- And be willing to concede. 'You are right that this is the weakest part of the thesis, which is why I would size it at half a normal position' is a far better answer than digging in. Interviewers push to see whether you update on evidence.
Where candidates lose it
Defending the pitch emotionally. This is a pressure test of intellectual honesty, not of conviction. The winning response quantifies the downside and names the exit; stubbornness reads as someone who will lose the fund money.
Expect next
- At what price would you stop out?
- How would you size the position?
- What is the single data point you would watch?

Firm tags come from public, anonymous candidate reports on Wall Street Oasis: strong signal, not sworn testimony. Firms are named as the places a question was reported, not as partners of Fin Maverick. Answers are written for this page to show how to think out loud; they are not scripts to recite.
