Summary

Had a system design/architecture round at Meta for a TPM role. One question, pretty open-ended, and I walked away feeling like I could have gone deeper on the tradeoffs.

Questions Asked (1)

Q1

Describe a time you were involved in designing system architecture. What components did you work with and what was your specific role?

Author's notes

I picked a project where I was more of a coordinator than a true architect and I think that hurt me.

Suggested Approach

Choose a specific project where you influenced system architecture as a TPM, and structure your answer using a clear framework like STAR. Focus on your unique contributions as a TPM—how you facilitated trade-off decisions, aligned cross-functional teams, and ensured the architecture met product goals—rather than deep technical implementation details.

Pro tip: Emphasize how you translated product requirements into architectural constraints and drove alignment among engineers, designers, and other stakeholders. Show that you understand the technical landscape well enough to ask the right questions and make informed trade-offs, but avoid claiming to have made engineering decisions yourself.

1. Set the Context

Briefly describe the project, its goals, and why architecture was critical. Mention the scale, constraints, and key stakeholders involved.

2. Define Your Role

Clearly state your specific responsibilities as a TPM in the architecture design process, such as gathering requirements, facilitating design discussions, or making trade-off recommendations.

3. Describe the Architecture and Components

Explain the high-level architecture and the main components (e.g., services, databases, APIs) you worked with, focusing on how they addressed product needs.

4. Highlight Trade-offs and Decisions

Discuss key technical trade-offs (e.g., scalability vs. cost, consistency vs. availability) and how you helped the team evaluate and decide on them.

5. Show Impact and Learnings

Summarize the outcome, including metrics or business impact, and reflect on what you learned about system design and cross-functional collaboration.

Key Points to Mention

  • Cross-functional collaboration: how you aligned engineering, design, product, and other teams
  • Technical trade-offs: specific examples like latency vs. throughput, build vs. buy, or monolith vs. microservices
  • Scalability and performance considerations: how the architecture supported growth or handled peak loads
  • Your specific role: facilitation, requirement definition, prioritization, or decision-making
  • Metrics or outcomes: how the architecture contributed to business goals (e.g., user engagement, revenue, efficiency)
  • Lessons learned: what you would do differently and how it shaped your approach to future projects
