Case studies in hiring: rigorous without being exploitative
The case round is where good processes shine and bad ones quietly rob candidates. The line is clearer than people pretend.
Case rounds are standard in banking and fintech hiring: analyze this book, price this product, design this launch. They are also the most abused stage - sprawling briefs, live business problems, days of expected work. The abuse is not just unfair; it selects for candidates with the most free time, not the most talent.
The fairness rules
- Bounded effort: state the expected hours and hold the line - two to four hours is usually enough
- Historical or hypothetical data, never the live problem the team is stuck on this week
- Everyone gets the same brief and the same deadline window
- Feedback offered to every candidate who submits
What to score
Structure first: is there a decision at the end, and does it follow from the analysis? Assumptions: named, reasonable, stress-tested? Practicality: could the institution actually do this? Communication: would this document survive a committee? Polish is last - you are hiring judgment, not formatting.
The live-case temptation
Using a real, current problem feels efficient. It is also transparent - senior candidates know when they are being mined - and it skews scoring toward whoever happens to know your sector's trivia. If the case must be real, pay for the work or cut the scope to a discussion. Your assessment should measure the candidate, not exploit them.
