They actually suggested sending over PR links beforehand so you can reference real code during the conversation, which I thought was a nice touch.
Select one or two projects where you faced a clear tradeoff (e.g., performance vs. maintainability, consistency vs. availability). For each, briefly describe the context, the options considered, the decision made, and the rationale, focusing on the tradeoffs and outcomes. Keep it concise and structured to highlight your decision-making process.
Pro tip: Quantify the impact of your tradeoff decisions (e.g., 'reduced latency by 30% at the cost of 10% higher memory usage') to demonstrate that you measure and own the consequences. Also, mention what you would do differently in hindsight to show growth and self-awareness.
Briefly describe the project, your role, and the key requirements or constraints that forced a tradeoff.
Explain the alternative solutions you considered and the specific tradeoffs between them (e.g., speed vs. cost, simplicity vs. flexibility).
Describe the criteria you used to choose one option, such as business goals, user impact, or technical debt, and why it was the best choice at the time.
Share measurable results (e.g., performance improvements, cost savings) and any negative consequences you accepted.
Mention what you learned and how you might approach similar tradeoffs differently in the future.
