Question 1

What happens in a guesstimate round?

Accepted Answer

Sara gives you one estimation question and you lead: pin down the scope, build a structure, state your assumptions, do the maths out loud and check that the answer makes sense. It is voice only, with no slides or spreadsheet.

Question 2

How long is it?

Accepted Answer

Easy is 10 minutes, Medium 15 and Hard 20.

Question 3

How is it scored?

Accepted Answer

On six areas: framing the problem (unit, geography and time frame), a clear structure before any numbers, assumptions you can defend, clean arithmetic, checking the answer against something you know, and communication that leads with the answer and ends with what it means for the business.

Question 4

Do I need to know the real numbers?

Accepted Answer

No. What counts is how you reason. Sara looks for assumptions you can justify and an answer you check against a known figure, not for one exact number.

Question 5

What do I get afterwards?

Accepted Answer

A report on your structure, numbers and communication, with the transcript and audio recording. A guesstimate round always ends with a report, even a short one.

Question 6

Can I take it again?

Accepted Answer

Yes, as often as you like. Each round is a single question, so a few in a row is quick practice.

Question 7

What does it cost?

Accepted Answer

Every new account gets free interviews to start. After that, a Day, Week or Month pass gives you unlimited interviews in every round until it ends.

Crack the guesstimate out loud.
