Decision-making, in the interview
Decision-making frameworks: 9 ways to structure a judgment answer
A judgment or hypothetical interview question has no single right answer, so it is scored on structure: what you weigh, in what order, and what would change your mind. These nine decision-making frameworks give that structure. Each page shows when one fits, a strong answer out loud, and problems to practice it on.
Which decision framework fits the question?
Read the question for one signal, then reach for the framework it points to. Several questions take two; name the main one and use the other as a check.
| If the question... | Reach for |
|---|---|
| asks whether to move now or wait, launch or hold | Reversible vs irreversible |
| is a personal or career choice with a long horizon | Regret minimization |
| describes a situation you have to read before you act | Cynefin |
| offers options with odds and payoffs | Expected value |
| asks how you would make a plan or a deal hold | Pre-mortem |
| frames two options as the only two | WRAP |
| sets a short-term gain against a long-term cost | 10/10/10 |
| has missing information and a deadline | The 70% rule |
| is a live crisis or a fast-moving conflict | OODA loop |
The nine frameworks
- Reversible vs irreversibleDecide fast when a choice can be undone, and slow down for the ones that cannot (Jeff Bezos' one-way and two-way doors).How to use Reversible vs irreversible
- Regret minimizationAsk which you would regret more in the long run: doing it, or not doing it (Jeff Bezos).How to use Regret minimization
- CynefinFirst name the situation: clear, complicated, complex or chaotic. In a crisis, act first; in a complicated case, analyze first (Dave Snowden).How to use Cynefin
- Expected valueWeigh each outcome by its odds: the chance of a gain times its size, minus the chance of a loss times its size.How to use Expected value
- Pre-mortemImagine the plan has already failed, list why, and build the defenses in now (Gary Klein).How to use Pre-mortem
- WRAPWiden your options, reality-test your assumptions, attain distance, prepare to be wrong (Chip and Dan Heath).How to use WRAP
- 10/10/10Ask how the choice will look in 10 minutes, 10 months and 10 years (Suzy Welch).How to use 10/10/10
- The 70% ruleDecide once you have about 70% of the information you wish you had, then adjust as you learn (Jeff Bezos).How to use The 70% rule
- OODA loopObserve, orient, decide, act, and loop again faster than the situation changes (John Boyd).How to use OODA loop
Decision frameworks in interviews: FAQ
Do interviewers expect you to name a decision framework?
No. They listen for structure, not vocabulary. Naming the framework in one short phrase can help the interviewer follow you, but the score comes from using it: stating the trade-off, weighing both sides and ending with a recommendation.
Which decision framework is most useful in a Google GCA interview?
Expected value and reversible vs irreversible cover most hypothetical questions, because they force you to put odds on outcomes and to ask what can be undone. For crisis scenarios, the OODA loop and Cynefin keep you from analyzing when you should act.
Can I combine two frameworks in one answer?
Yes, and strong answers often do: Cynefin to read the situation, then expected value to choose. Keep one as the spine of the answer so it does not turn into a list of models.
