Your question is Deep Dive Into a 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).
Tell me about a project from your resume that you can deeply explain, including your exact contribution, the technical challenges you faced, why you chose specific technologies, and how you optimized the solution. Choose a project where you personally made meaningful technical decisions, not one where you only supported the work. Be prepared to explain the original requirements, alternatives you considered, trade-offs, bottlenecks, validation methods, and measurable results. I may ask follow-up questions about implementation details, failure modes, collaboration, and what you would change in retrospect.
