Your question is Project Deep Dive. 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).
Tell me about the project you have mentioned on your resume in detail. I want to understand what problem you were solving, what your specific role was, and how you made decisions along the way. Focus on your contribution, tradeoffs, and the outcome, not just the project name or a high-level summary.
