Walk me through your current role at Acme — what do you own day to day, and how big is the team and system you work on?

Clear ownership of a meaningful surface, concrete scope (services, team size, scale), and language that matches a senior IC.

Vague or title-only description, unclear what they personally own vs. the team, or scope that reads more mid-level than senior.

Can't describe their own responsibilities, contradicts their résumé, or scope is far below a Sr. Software Engineer.
