Every candidate flubs a calculate step eventually. Interviewers care what you do next. Freezing, apologizing, or restarting from zero burns the rest of the case.

Build a recovery script so a bad intermediate does not end the interview.

The 20-second recovery

1. Name it: "That intermediate looks off. I'll re-check the setup."
2. Isolate: restate the equation in one line (price times volume, not a new framework).
3. Re-chunk: calculate one piece again out loud, then the next.
4. Land the so-what: even with a rough number, say fact, meaning, decision.

Drill it this week

• Set a 3-minute timer on a market-sizing prompt.
• Intentionally mess up the first intermediate, then run the recovery script.
• Finish with a recommendation and the biggest risk.

Silent worksheets never teach recovery. Voice drills do.
