Design an asynchronous service that converts text input into video output, focusing on scalability and efficiency.
This question is commonly asked in onsite interviews for software engineering roles at OpenAI to assess a candidate's ability to design complex systems. The interviewer evaluates the candidate's understanding of asynchronous processing, scalability, and the integration of various technologies to create a seamless user experience. The candidate's ability to think critically about system architecture and potential bottlenecks is also key.
What the Interviewer Expects
- Identify and clarify requirements for the text-to-video generation service.
- Outline a high-level architecture that includes key components and their interactions.
- Discuss potential challenges and trade-offs in design decisions.
- Explain how to ensure scalability and reliability of the service.
- Consider user experience and response time in the design.
Key Topics to Cover
How to Approach This
- Start by clarifying functional and non-functional requirements with the interviewer.
- Estimate the scale: QPS, storage, bandwidth. This drives your design decisions.
- Draw a high-level architecture first, then deep dive into 1-2 critical components.
- Discuss trade-offs explicitly (e.g., consistency vs availability, SQL vs NoSQL).
- Address failure scenarios, monitoring, and how the system handles 10x traffic spikes.
Possible Follow-up Questions
- How would you handle errors in the video generation process?
- What technologies would you choose for the backend and why?
- How would you optimize the service for cost efficiency?

Requirements
To design an asynchronous text-to-video generation service, we first need to gather requirements. Key functionalities include:
- Input: Users can submit text prompts.
- Output: The service gen...
High-Level Design
The architecture can be broken down into several components:
- Frontend: A user interface for text input and video playback.
- API Gateway: Manages requests and routes them to appropriate se...
