Your question is Cold Call to Hiring Manager. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Call a hiring manager to pitch why they should hire you.
Treat this as a live sales role-play. Demonstrate discovery, position your experience around the hiring manager's likely business needs, handle skepticism, and earn a clear next step. Do not deliver a generic personal introduction. Explain how you would prepare, what you would say, which questions you would ask, and how you would close the call.
