Mistakes to Avoid
- Focusing on perfecting a single system design rather than practicing a variety of scenarios (BAD: "I've memorized the perfect architecture for an e-commerce platform"; GOOD: "I've practiced designing systems for different e-commerce challenges")
- Neglecting to consider business impact and ROI in system design decisions (BAD: "My design is technically perfect, but it costs 10 times more than the current system"; GOOD: "My design balances technical requirements with business constraints")
- Failing to communicate complex technical ideas clearly and concisely (BAD: "The system uses a distributed architecture with microservices and load balancers"; GOOD: "We can handle increased traffic by adding more nodes to our cluster, which is behind a load balancer")
