How to answer
One candidate reported on Aced, in a listing dated April 2026, that their Cognition AI process included a presentation explaining a real technical project to people at different levels.

Build it in layers, not as two talks. Every section opens with a sentence the executive can repeat, then goes one layer down for the engineers.
- Outcome first. Who had the problem, what it cost them, and what changed, with a number.
- The constraint that shaped everything, in the customer’s words.
- One diagram and one decision. The options you weighed and why the winner won. Then signpost the layer change: “Here’s how it works underneath.”
- Your part, in one precise sentence.
- What broke, how you found it, and what you changed.
- Close on the outcome again, and what you’d do next.
In questions, answer at the asker’s layer. Give an executive business terms first, then offer the detail. Give an engineer the mechanism, drawn if you can. When a question probes your part, be exact about what you decided and what you inherited. When you don’t know, say what you’d check.
The trap is aiming at one person. Pitch to the executive alone and the engineers have nothing to test; pitch to the engineers alone and the executive stops following.
Follow-ups
What the interviewer may ask next, once your first answer is on the table.
- From the executive: was it worth what it cost, and would you do it again?
- From the engineer: why not the simpler option? Draw where it would have broken.
- Which of the decisions on that slide were yours, and which did you inherit?
Where answers go wrong
- Pitching the whole talk at the most senior person in the room, so the engineers get no decision to test, or at the engineers, so the executive loses the thread by the second diagram.
- Answering every question at the same depth, so the executive gets a lecture on ordering guarantees and the engineer gets a business summary.
