> "So, do not jump right in to give a solution. Slow down. Think deeply and ask questions to clarify requirements and assumptions. This is extremely important." > "In a system design interview, giving out an answer quickly without thinking gives you no bonus points." **Source**: Alex Xu - *System Design Interview – An Insider's Guide* ## Context The impulse to demonstrate competence by answering quickly is counterproductive in system design interviews. Thoughtful analysis is valued over speed. ## Why Slowing Down Helps - **Better understanding**: Uncover hidden requirements - **Avoid rework**: Don't design for wrong constraints - **Show process**: Demonstrate structured thinking - **Build rapport**: Create collaborative discussion ## Practical Techniques 1. **Repeat the problem**: "So you want me to design..." 2. **Ask clarifying questions**: Even if you think you know 3. **State assumptions**: "I'm assuming X, is that correct?" 4. **Outline approach**: "I'll start with requirements, then..." 5. **Check in periodically**: "Does this direction make sense?" ## Anti-Pattern Immediately drawing boxes and arrows without establishing what you're building or for whom. ## Related Concepts - [[Requirements First]] - [[Interview Evaluation Criteria]] - [[Over-Engineering Red Flag]] ## Tags #system-design #interviews #process
