Tell me about a time when you had to implement a solution to a problem without precedent. How did you approach it?
Instruction: Describe a problem with no established solution in your team or context. Explain what made it unfamiliar, how you tested your approach and the result.

Illustrative answer
This fictional example concerns a problem new to the team, not a claim that nobody had solved it before.
Our operations team had to reconcile records from a newly acquired service, and we had no agreed process for its identifiers and status history. I was responsible for proposing the first workflow. The dangerous shortcut would have been to assume that similar-looking records represented the same event.
I asked the service owner to explain the data lifecycle and reviewed analogous reconciliation processes with our own team. We separated known mappings from unresolved cases and agreed which evidence could justify a match. Where an identifier was missing or conflicting, the case would remain an exception for review.
I built a small, authorized sample containing straightforward matches, duplicate records and conflicting statuses. We manually established expected results with the owners, then tested the proposed workflow against them. One rule merged distinct events, so I removed it and documented why that apparent shortcut was unsafe.
The first controlled run produced supported matches and a visible exception queue. It did not resolve every historical inconsistency, and those cases retained named owners. I learned that unfamiliar work benefits from a clear uncertainty boundary, analogous expertise and small falsifiable tests before broad execution.
Follow-up to practice
What did you decide not to automate, and what additional evidence would change that decision?
