Your question is Leadership Through Past Projects. 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).
Walk me through your previous work experience and the projects you have led.
Focus on one or two backend projects where you had meaningful ownership, rather than listing every role or technology. Explain the problem, your responsibilities, how you prioritized work and aligned others, the outcome, and what you learned.
