Tell me about a time you went beyond your responsibilities

Describe a time you took on a problem nobody had assigned to you: an inefficient team process you fixed, a tool that helped teams beyond your own, a risky project you owned end to end, or an initiative you organized across stakeholders. Explain why you stepped in, what you did, who you had to bring along, and the impact.

A good answer shows ownership of the long-term outcome, not just extra hours, with a concrete result.
