← Applied intuition Interview Insights
The interviewer made it pretty clear early on that he wasn't impressed.
Start by clarifying the problem's functional and non-functional requirements, then sketch a high-level design before diving into component details. Iterate through scalability, trade-offs, and bottlenecks, and always tie decisions back to the requirements and constraints.
Pro tip: Drive the conversation by stating your assumptions explicitly and asking the interviewer to confirm them—this shows collaboration and prevents you from solving the wrong problem. Also, proactively discuss trade-offs and alternatives, not just your chosen solution.
Ask questions to understand the problem's scope, functional requirements (e.g., features, users), and non-functional requirements (e.g., scale, latency, consistency, availability).
Sketch the main components (e.g., clients, servers, databases, caches, queues) and how they interact. Keep it abstract and focus on data flow.
Elaborate on critical components: data storage (SQL vs NoSQL), APIs, scaling strategies (sharding, replication), and handling bottlenecks.
Discuss trade-offs (e.g., consistency vs availability, latency vs cost) and identify potential bottlenecks (e.g., single points of failure) with mitigation strategies.
Recap the design, highlight how it meets requirements, and suggest improvements or next steps based on feedback.
