Calibration Drills for Estimation
Calibration drills for estimation interviews, covering confidence buckets, estimate logs, outcome checks, interval widening, and review.
Candidates who need confidence ranges that match reality.
Calibration compares confidence with outcomes
If you say an interval should contain the truth 80 percent of the time, it should actually contain the truth about that often across many attempts.
Keep an estimate log
Record the prompt, estimate, confidence range, actual value when available, and whether the actual value fell inside the range.
Concrete drill
Make ten estimates with 80 percent confidence intervals, then check actuals later. If only four contain the truth, the intervals are too narrow.
Adjust deliberately
Widen ranges for categories where you are overconfident and narrow them only after repeated evidence that your ranges are too wide.
Common mistakes
Candidates often treat calibration as a feeling. It improves through logged estimates and feedback, not confidence alone.
Practice the pattern
