Guesstimate

Consulting and banking interviewers love “Estimate how many…”. You do not need the exact number. Get the scale right and you win.

Five estimates. Slide to your number. The closer to the reference, the more points: within 2× is close, 10× off is a different scale. Each question shows one way to break it down.

• ≤ 1.5×Spot on
• ≤ 2×Close
• ≤ 3×Right scale
• > 10×Way off

• 5 estimates
• About 2 min
• Result you can share

Made up. Do not treat it as career advice.
