Live Explain-to-Audience Exercise

What it tests

Real-time audience adaptation — the single most important DevRel skill — by putting the candidate in an improvised teaching scenario with a defined fictional audience.

Format

1. 1Interviewer presents a scenario on the spot: 'Explain [technical concept] to [specific audience]' — e.g., 'Explain distributed tracing to a backend engineer who's never used observability tools'
2. 2Candidate explains without preparation time — exactly as they would at a conference or in a customer call
3. 3Interviewer plays the audience character, asking 'naive' questions or escalating complexity to test adaptation range
4. 4Brief debrief: interviewer reveals the character's actual background and asks the candidate how they'd adjust

What to look for

• Does the candidate clarify the audience's background before diving in — great advocates ask before they talk
• Concrete analogies over jargon: can they explain it in a way that doesn't require knowing the answer already
• Recovery when they misjudge the audience — do they adjust gracefully or double down
• Energy and presence — developer advocacy is a performance craft, and flat delivery is a real signal

Adaptation guide

Run this exercise twice with two different audience types (e.g., a junior developer and a non-technical executive) to see whether the candidate can genuinely shift register, not just simplify vocabulary. Choose a technical concept from your actual product for maximum relevance.
