Describe a time you built something without clear requirements

Question

Meta expects engineers to operate with ambiguity. Walk through a project where the scope or direction was unclear, how you defined the problem yourself, and how you drove it to completion.

The interviewer is assessing your ability to navigate ambiguity and take initiative in defining project scope. They want to understand how you approach problem-solving when requirements are unclear and how you drive projects to completion despite the lack of guidance.

1. **Context**: Briefly describe the project and the ambiguity involved.  
2. **Problem Definition**: Explain how you identified key issues despite unclear requirements.  
3. **Action Taken**: Detail the steps you took to define the project scope and drive it forward.  
4. **Outcome**: Share the results of your efforts and what you learned from the experience.

In my previous role at a tech startup, I was assigned to develop a new feature for our mobile app, but the requirements were vague and constantly changing. I took the initiative to set up meetings with stakeholders to understand their underlying needs and pain points. Through these discussions, I identified that users struggled with navigation, which wasn't part of the initial scope. I gathered feedback from users and created a prototype that addressed these navigation issues. I then collaborated with designers and developers to refine the prototype into a working feature. After several iterations, the feature was launched and led to a 20% increase in user engagement. This experience taught me the importance of proactive communication and user-centric design, especially in ambiguous situations.

The interviewer wants to hear about your proactive approach in a situation with unclear direction. Good responses will highlight your initiative in seeking clarity, your problem-solving skills in defining the project scope, your ability to collaborate with others, and the positive impact of your work. They look for metrics or concrete outcomes that demonstrate success.

Common pitfalls include failing to take responsibility for ambiguity, providing vague or overly general responses, not specifying actions taken, or neglecting to quantify outcomes. Additionally, candidates may describe a situation without focusing on their personal contributions or insights gained, which diminishes the impact of their answer.
