Choose a specific project where you drove technical direction, and structure your answer using a narrative arc: context, decision, trade-offs, and impact. Emphasize how you aligned stakeholders and prioritized roadmap items to achieve measurable results.
Pro tip: Quantify the impact of your technical direction (e.g., reduced latency by X%, saved Y engineering hours) and explicitly mention how you incorporated feedback from stakeholders to refine the direction.
Briefly describe the team, project, and why technical direction was needed. Highlight the scale and ambiguity of the problem.
Explain how you evaluated options, including technical trade-offs (e.g., performance vs. maintainability) and gathered input from stakeholders.
State the technical direction you set, and justify it with data and reasoning. Mention how you communicated it to the team.
Describe how you ensured buy-in, prioritized tasks, and managed dependencies or resistance during implementation.
Share the measurable impact (e.g., performance improvements, delivery speed) and what you learned about setting direction.
AI-generated suggestions, not part of the candidate's original notes. May be inaccurate — verify before relying on them.
Choose a disagreement where you had a strong technical or product rationale, but ultimately supported the final decision. Focus on how you voiced your concerns constructively, sought to understand the leadership perspective, and committed to the outcome. Emphasize the positive resolution and any lessons learned about cross-functional alignment.
Pro tip: Show that you can disagree without being disagreeable: explicitly state that you escalated with data, not emotion, and that you supported the decision once it was made. This demonstrates maturity and the ability to execute even when you disagree.
Briefly describe the project, your role, and the leadership decision you disagreed with. Keep it concise and focus on the technical or strategic aspects.
Articulate why you disagreed, using data, user impact, or technical trade-offs. Show that your concern was well-reasoned and aligned with company goals.
Explain how you raised your concerns respectfully and constructively. Mention if you sought feedback, prepared a counter-proposal, or used data to support your position.
Describe the outcome: how leadership responded, whether you reached a compromise, and how you committed to the final decision. Highlight any positive results or lessons learned.
Summarize what you learned about communication, alignment, or decision-making. Show that you grew from the experience and can apply it in future situations.

I went with something real, a project that shipped late and caused downstream pain for another team.
Choose a failure that is significant but not catastrophic, where you took ownership and drove a clear learning outcome. Use a structured narrative (e.g., STAR) to describe the situation, your actions, the impact, and what you changed afterward. Emphasize root cause analysis and how you adapted to ambiguity, tying it to engineering practices at Meta.
Pro tip: Avoid blaming others or external factors; instead, highlight your personal accountability and the systemic improvements you implemented. Show that you turned the failure into a repeatable process or safeguard that benefits your team.
Briefly describe the project, your role, and the goal, providing enough background for the interviewer to understand the stakes. Keep it concise to leave time for the failure and learnings.
Clearly state what went wrong, including the impact (e.g., outage, missed deadline, data loss). Be specific about your actions or decisions that contributed to the failure.
Explain how you investigated the failure to identify the underlying cause(s), using tools like the 5 Whys or fishbone diagram. Show that you didn't just treat symptoms.
Describe the steps you took to mitigate the failure and prevent recurrence, such as implementing safeguards, improving processes, or enhancing monitoring. Highlight collaboration and communication.
Summarize what you learned and how you applied it to future projects. Connect it to broader engineering principles or Meta's values, showing maturity and adaptability.

Focused on a senior engineer I worked with on code review ownership.
Choose a specific mentee and situation where you made a tangible difference in their growth. Use the STAR method to structure your story, emphasizing your actions and the results for both the mentee and the team. Highlight how this experience demonstrates your ability to lead and collaborate effectively.
Pro tip: Focus on how you tailored your mentoring approach to the individual's needs and how you measured their progress, showing empathy and data-driven thinking. Also, briefly mention what you learned from the experience, demonstrating humility and continuous improvement.
Briefly describe the team, the mentee's role, and the challenge they were facing. Explain why mentoring was needed and what the goal was.
Detail the specific steps you took to mentor the person, such as regular 1:1s, pair programming, code reviews, or creating a growth plan. Emphasize how you tailored your approach to their needs.
Share concrete results: how the mentee improved, any promotions or increased responsibilities, and the positive effect on the team or project.
Summarize what you learned and how it demonstrates your ability to grow others, aligning with Meta's values like 'Focus on Impact' and 'Move Fast'.
