I picked a story I thought was solid but halfway through realized I was talking way too much about the technical details and not enough about my actual role in getting the team there.
Choose a specific architecture decision where you can clearly articulate the problem, the options considered, and the trade-offs. Emphasize your role in driving alignment across teams and how you measured success. Highlight the decision's impact on scalability, reliability, or business metrics, especially in a high-scale environment like Uber.
Pro tip: Quantify the impact with concrete metrics (e.g., latency reduction, cost savings, incident reduction) and acknowledge what you'd do differently in hindsight to show self-awareness and growth.
Briefly describe the system, the team's goal, and the constraints (e.g., scale, latency, cost) that made the decision critical.
Outline the options evaluated, the criteria used (e.g., scalability, maintainability), and how you involved cross-functional partners.
Describe the selected solution and the key trade-offs made, explaining why it was the best fit for the constraints.
Explain how you built consensus, addressed concerns, and ensured buy-in from stakeholders like product, SRE, and other engineering teams.
Quantify the impact (e.g., performance, cost, reliability) and reflect on what you learned or would improve next time.
