Summary

Interviewed for an EM role at Uber, got a behavioral/leadership round with a focus on technical decision-making from a people manager angle. Just the one question shared here but it was meaty enough to chew on for a while.

Q1

Tell me about a time your team made a particularly strong system architecture decision.

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.

Suggested Approach

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.

1. Set the Context

Briefly describe the system, the team's goal, and the constraints (e.g., scale, latency, cost) that made the decision critical.

2. Explain the Decision Process

Outline the options evaluated, the criteria used (e.g., scalability, maintainability), and how you involved cross-functional partners.

3. Detail the Chosen Architecture

Describe the selected solution and the key trade-offs made, explaining why it was the best fit for the constraints.

4. Highlight Cross-functional Alignment

Explain how you built consensus, addressed concerns, and ensured buy-in from stakeholders like product, SRE, and other engineering teams.

5. Share Results and Learnings

Quantify the impact (e.g., performance, cost, reliability) and reflect on what you learned or would improve next time.

Key Points to Mention

  • Specific trade-offs considered (e.g., consistency vs. availability, latency vs. cost)
  • How you measured success with metrics (e.g., p99 latency, error rate, infrastructure cost)
  • Cross-functional collaboration and alignment process (e.g., design reviews, RFCs)
  • Scalability and reliability improvements for high-volume traffic
  • Your personal contribution and leadership in the decision
  • Lessons learned and how you applied them to future projects
