Hypothesis-driven thinking

Start with a guess, then test it.

Instead of analysing everything, state your best guess early (‘I think this is a cost problem’) and use data to prove or disprove it.

It's faster and makes your reasoning visible to the interviewer.

🧮 Example

“My hypothesis is rising delivery costs are squeezing margins. To test it, I'd like cost per order over two years.”

🎯 Interview tip

Say your hypothesis in the first two minutes — and change it confidently when data disagrees.
