Tell me about a time you missed a deadline

Why interviewers ask this

Deadlines get missed on every team eventually — what matters is whether you saw it coming early and communicated it, or let it become a surprise for everyone depending on you.

What a strong answer covers

• Why the deadline was missed — underestimated scope, an unexpected dependency, competing priorities — stated honestly without over-blaming external factors
• When you realized it was at risk, and what you did the moment you knew — this is the crux of the question; escalating early is a good answer, going quiet until the deadline arrives is a bad one
• How the actual miss was handled — did you renegotiate scope, get help, or just ship late with no communication?
• What you changed about your estimation or communication process afterward

Common pitfalls

• A story where you only mention the deadline was missed, with no detail on when you knew and what you did about it
• Blaming the estimate entirely on someone else without describing your own role in catching it late or early
