Degraded dependency fail-open decision
An internal dependency your service calls is degraded (slow, partial errors) but not fully down. You must decide whether to fail open (proceed without it) or fail closed (block). How do you reason about it?
What a strong answer looks like
Stop the bleeding first (mitigate), then form hypotheses from real signals. Separate root cause from symptom, communicate status as you go, and close with what prevents a repeat.

Which questions mattered is sealed until you submit. Telling you now would just be handing over the edge cases.
