How do you explain a hard decision in two minutes?
Answer out loud or in your head first, then compare.
Answer
I start with the problem and my choice. Then I give the most important reason, the main cost of the decision and how the result will be checked. I don't have to list all the tools and possible exceptions straight away.
For example: “The limit has to be shared and mustn't drift. So I make the decision to take a spot at a single owner of the state. That adds a round trip to that place, so I'd check the response time and the behaviour on failure.” Then I let the interviewer ask follow-ups. If I don't remember a project detail, I say so and point to what needs checking. An understandable answer beats a list of correct-sounding names with no link to the decision.
Why it matters: Prepares you for a natural conversation, not reciting definitions.
Possible follow-ups: How would you explain the same decision to a non-technical person?
How did it go? Be honest — “Not yet” puts the question on your review list.
