Case Discussion: Guestimates

Mastering Guestimates – The Art of Structured Estimation

Guestimates are more than just quick math—they’re a test of how you think under pressure, structure ambiguity, and communicate logic clearly. In consulting and strategy interviews, a well-structured guestimate can make or break your impression.

In this session, I’ll walk you through a proven, structured approach to crack guestimates with confidence and clarity. With real examples, industry-specific problems, and personalized feedback, you’ll learn how to:

🔹 Break down vague questions into solvable buckets

🔹 Choose the right approach (top-down/bottom-up) based on the scenario

🔹 Make logical assumptions and back them with reasoning

🔹 Present your thought process clearly and confidently to an interviewer

🔹 Avoid common traps like overcomplicating or rushing through numbers

Having coached peers through consulting shortlists, case prep bootcamps, and live competition rounds, I bring insights from both sides—as a candidate and a mentor. Whether you’re facing interviews at MBB, Big 4, or high-growth startups, this session will help you turn “random guesses” into “rational estimates.”

Let’s decode the numbers—and impress with the process.
