HearQA for System Design Interviews
Design distributed systems with confidence. Get real-time architecture suggestions and trade-off analysis from your phone.
무료로 시작하기일반적인 과제
System design questions are broad and it is difficult to know where to start
Interviewers expect you to discuss trade-offs for decisions you make in real time
Scaling requirements change mid-discussion and you need to adapt quickly
Drawing architecture diagrams while explaining concepts splits your attention
Each company tests different aspects: some focus on API design, others on distributed systems
HearQA가 돕는 방법
Architecture Pattern Suggestions
When a system design problem is presented, HearQA suggests relevant architecture patterns, component choices, and a structured approach to walk through the design methodically.
Trade-Off Analysis
As you make design decisions, the AI surfaces relevant trade-offs — consistency vs availability, SQL vs NoSQL, monolith vs microservices — with concise talking points.
Reference Material Integration
Upload your system design study materials — Grokking System Design, DDIA notes, or your own summaries. The AI references these during the interview for specific numbers, patterns, and best practices.
Whiteboard Capture
Use video & camera capture to photograph the whiteboard or shared drawing. The AI analyzes the current diagram and suggests improvements, missing components, or potential bottlenecks.
