This is not a question you can grind leetcode for.
Acknowledge the PM's comments and questions to show you value their input, then systematically address each concern by clarifying your technical reasoning, explaining trade-offs, and proposing alternatives where appropriate. Frame the response as a collaborative effort to align on the best solution for the product and users.
Pro tip: Use a structured format like a table or bullet points to map each concern to your response, making it easy for the PM to follow and respond. Also, proactively offer to discuss live if the written response becomes too lengthy or complex.
Start by thanking the PM for their detailed feedback and acknowledging the importance of their concerns. This sets a collaborative tone and shows you're not defensive.
For each technical decision, explain the rationale in simple, non-technical terms, focusing on how it benefits the product or addresses constraints. Avoid jargon and relate it to business or user impact.
Directly address each concern, explaining any trade-offs considered (e.g., performance vs. development time). Be transparent about limitations and why certain decisions were made.
Where feasible, suggest alternative approaches that might address the PM's concerns, outlining pros and cons. If no alternative is viable, explain why and propose a path forward.
Suggest a follow-up discussion or a decision point to ensure alignment. Offer to provide more details or to collaborate on a solution.
