What the interviewer is really asking

Assess communication clarity and ability to tailor technical explanations to the audience.

What to say

• Describe who the audience was and what their technical baseline looked like.
• Walk through how you chose analogies, visuals, or simplified language.
• Share whether they understood and how you confirmed it.

What to avoid

• Don't describe 'dumbing it down' dismissively — frame it as adapting to the audience.
• Avoid just reciting jargon and hoping they got it.
• Don't skip confirmation — a great communicator checks for understanding.

Example answers

Strong: A product manager asked why a caching layer was necessary. I compared the database to a library and the cache to sticky notes on your desk — you write down the answer you looked up rather than walking to the library every time. She immediately understood the latency argument and was able to explain the trade-off to the client herself.

Weak: I sent them a link to the technical documentation and said it was all in there.
