Your question is Explaining Your Most Relevant 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).
Pick one project, certification, or piece of coursework from your background that best prepares you for this role, and walk me through it. Why did you choose it, what was your specific contribution, what impact did it have, and what would you do differently now?
