Describe a decision you had to make before you could get the information you wanted. How did you decide, and how did it play out?

Most real decisions are made under uncertainty; this question separates candidates who can reason about reversibility, cost of delay, and what evidence is worth buying from those who either freeze or gamble.

• What information did you decide not to wait for, and why?
• How would you have known you were wrong early?
• What did the decision cost or save compared to waiting?

The candidate names the trade-off explicitly (delay vs. risk), distinguishes reversible from irreversible calls, and set up some way to detect being wrong early.

The story is really about luck, the candidate can't articulate why waiting was worse, or "gathering more data" is treated as free.
