For Product Managers · Early-stage prep
Capital One PM Mini-case prep
If a recruiter has just reached out about a Product Manager role, the Mini-case is often the first real practice target — before the Power Day. This page is for that stage: how to approach it. Formats vary by role, so confirm the details of your loop with your recruiter.
How to approach a PM Mini-case
1. Restate the goal before you calculate
Say back what decision the numbers are meant to support. A clean answer to the wrong question is the most common early miss.
2. Name your assumptions out loud
When a number is missing, choose a round, defensible value and say why. Interviewers care more about how you reason than whether your guess matches theirs.
3. Write the math so someone can follow it
Lay out one line per step: what you are computing, the formula, the result with units. Check the order of magnitude before moving on.
4. Turn the number into a recommendation
End with a decision, the main risk, and what you would measure next. A number with no “so what” reads as unfinished.
5. Expect “why?” more than once
Follow-ups usually probe an assumption or ask what changes if one input moves. Practice saying what would make you change your mind.
Practice both stages: Mini-case, then Power Day
The program covers Mini-case business and math problems plus the product, technical, data and leadership conversations of a Power Day — with follow-ups, worked guidance, optional timers and saved revisions.
