I went with the restaurant analogy (waiter takes your order to the kitchen, brings back food) and it landed fine.
Use a relatable analogy like a restaurant menu or a waiter to explain how an API acts as an intermediary that lets two systems communicate without knowing each other's internal details. Then, connect it back to a real-world example such as ordering food through a delivery app, and finally emphasize the benefits like abstraction, security, and efficiency.
Pro tip: Show that you can tailor your explanation to the audience's level by avoiding jargon and checking for understanding; this demonstrates communication skills that are highly valued at Meta, where engineers often explain technical concepts to non-technical stakeholders.
Start with a one-sentence definition: an API is a set of rules that allows two software programs to talk to each other. Avoid acronyms or technical jargon.
Compare an API to a restaurant waiter: you (the app) tell the waiter (API) what you want from the kitchen (server), and the waiter brings it back without you needing to know how the kitchen works.
Describe a familiar scenario, like using a travel app to book a flight: the app uses an airline's API to check availability and make a reservation, without accessing the airline's internal database directly.
Explain why APIs matter: they save time, improve security by limiting access, and allow different systems to work together seamlessly, even if built by different companies.
Ask if the explanation makes sense and offer to clarify any part, showing that you value clear communication over just delivering information.

Two questions in one, which I didn't love.
Use the STAR method to structure two distinct stories: one highlighting successful collaboration and another addressing conflict resolution. For the difficult coworker, focus on empathy, data-driven communication, and a positive outcome that improved the working relationship.
Pro tip: Emphasize how you turned the difficult coworker situation into a learning opportunity and strengthened the team, rather than just complaining about the person.
Briefly describe the team project and your role, ensuring relevance to software engineering at Meta.
Use STAR to narrate a time you collaborated effectively, focusing on your contributions and the team's achievement.
Transition to the difficult coworker scenario, objectively describing the issue without blaming.
Explain the steps you took to resolve the conflict, such as active listening, finding common ground, or involving a mediator.
Conclude with the positive result and what you learned about communication and teamwork.

Genuinely hard to answer without sounding either fake-humble or like you're throwing a past employer under the bus.
Choose a real, meaningful mistake that you've genuinely learned from—ideally one with clear consequences but not so severe it raises red flags. Structure your answer to show accountability, the specific lesson learned, and concrete changes you've made to your work habits. Emphasize how this experience made you a more effective and resilient engineer.
Pro tip: Pick a mistake that is relatable but not disqualifying, and focus more on the systemic fix you implemented than on the error itself. Meta values impact and learning velocity, so highlight how your change improved team outcomes or prevented similar issues.
Describe the situation and your role without over-explaining. Keep it concise so you can spend most of the time on the learning and change.
Clearly state what you did wrong and its impact, taking full responsibility without blaming others or external factors.
Explain what you learned from the mistake—focus on a transferable insight about engineering, communication, or process.
Detail the specific actions you took to change how you work, such as new habits, tools, or processes you adopted.
Share how your change led to better results, such as improved code quality, faster delivery, or stronger team collaboration.

Select a project where you drove measurable impact, ideally one that required balancing technical trade-offs and aligning stakeholders. Structure your answer using a clear narrative arc: context, challenge, your actions, and quantified results. Emphasize your specific contributions and the decisions you made that led to success.
Pro tip: Quantify impact with metrics that matter to Meta (e.g., user engagement, performance improvements, revenue impact) and explicitly connect your technical choices to those outcomes. Show how you navigated ambiguity and influenced without authority.
Briefly describe the project, your role, and why it mattered to the business or users. Keep it concise to leave time for your actions and impact.
Explain the key technical or organizational obstacle you faced, such as scalability limits, conflicting stakeholder priorities, or tight deadlines.
Walk through the specific steps you took, focusing on technical trade-offs you evaluated and how you managed stakeholders to gain alignment.
Share concrete results using metrics (e.g., latency reduction, user growth, cost savings) and tie them back to your actions.
Summarize what you learned and how it relates to the role at Meta, showing self-awareness and growth.
