Jun 2026

Summary

Behavioral round at Uber for a software engineering role, basically one big question about your proudest project but with a lot of layers to it. Not a bad experience, just more structured than I expected.

Questions Asked (1)

Q1

Walk me through the project you're most proud of or consider your most impressive work. Cover the business and technical context, your specific contributions, the key technical decisions and trade-offs you made, the measurable impact, and what you'd do differently looking back.

Suggested Approach

Choose a project that demonstrates end-to-end ownership and aligns with Uber's scale and data-driven culture. Structure your answer using a narrative arc: context, problem, your role, technical decisions with trade-offs, measurable impact, and lessons learned. Emphasize how you balanced competing constraints (e.g., latency vs. cost, consistency vs. availability) and used metrics to validate decisions.

Pro tip: Quantify impact with specific metrics (e.g., 'reduced p99 latency by 40%' or 'increased conversion by 2%') and tie them to business outcomes like revenue or user retention. Also, be candid about what you'd do differently—it shows self-awareness and growth mindset, which Uber values.

1. Set the Context

Briefly describe the business problem, the product, and the technical environment (e.g., scale, stack, team size). Explain why this project mattered to the company.

2. Outline Your Role and Contributions

Clarify your specific responsibilities and what you personally built or led. Avoid vague 'we' statements; highlight your individual impact.

3. Detail Key Technical Decisions and Trade-offs

Walk through 1-2 critical decisions (e.g., architecture, algorithm, database choice) and explain the alternatives, constraints, and why you chose your approach. Discuss trade-offs like latency vs. consistency, cost vs. performance.

4. Quantify Measurable Impact

Present concrete metrics (e.g., performance improvements, cost savings, user engagement) and connect them to business goals. Use numbers to make your impact tangible.

5. Reflect on What You'd Do Differently

Share 1-2 lessons learned or alternative approaches you'd consider now. Show that you've grown from the experience and can apply those insights to future projects.

Key Points to Mention

  • Business context and why the project was important (e.g., revenue impact, user growth)
  • Technical complexity and scale (e.g., millions of requests per second, distributed systems)
  • Specific technical trade-offs (e.g., CAP theorem, caching strategies, microservices vs. monolith)
  • Measurable outcomes with metrics (e.g., reduced latency by X%, increased throughput by Y%)
  • Your individual contributions and leadership (e.g., led design, mentored engineers)
  • Lessons learned and how you'd improve the approach (e.g., better testing, different tech stack)
