Your question is Talk Through a Past Project. 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).
Talk about a project you have done before, focusing on your role and impact. Choose one specific project and explain the situation, your responsibilities, the actions you personally took, and the measurable outcome. Be clear about your individual contribution rather than describing only what the broader team accomplished.
