Your question is Resolving Project Bottlenecks. 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).
What are the specific technical problems and bottlenecks you encountered during your projects, and how did you resolve them?
Focus on one or two concrete embedded engineering examples. Explain the technical symptoms, your diagnosis, the trade-offs you considered, how you coordinated with others, and the measurable result. Be clear about your personal contribution, any assumptions you revised, and what you would improve in a future project.
