I'm applying for a Senior Frontend Developer position at a tech startup that focuses on building real-time collaboration tools.

I'll conduct a technical interview for the Senior Frontend Developer position. Here are 6 questions with guidance:

Question 1: System Design

"How would you design a real-time collaborative text editor that supports multiple users editing simultaneously?"

Key Points to Address:
- Operational Transform (OT) or Conflict-free Replicated Data Types (CRDTs)
- WebSocket connections for real-time communication
- Conflict resolution strategies
- Scalability considerations

30-Second Answer Framework:
"I'd use WebSockets for real-time communication, implement CRDTs for conflict resolution, and design a microservices architecture with Redis for session management."

Instant Feedback: Mention specific technologies like Yjs or ShareJS libraries to show depth.

Question 2: JavaScript Fundamentals

"Explain the difference between `let`, `const`, and `var` in JavaScript, and when you'd use each."

Key Points to Address:
- Block scoping vs function scoping
- Hoisting behavior
- Temporal dead zone
- Immutability considerations

30-Second Answer Framework:
"`var` is function-scoped and hoisted, `let` is block-scoped with temporal dead zone, `const` is block-scoped and immutable. Use `const` by default, `let` for reassignment, avoid `var`."

Instant Feedback: Provide a code example showing the temporal dead zone to demonstrate practical understanding.

Question 3: React Performance

"How would you optimize a React component that renders a large list of items?"

Key Points to Address:
- Virtualization (react-window/react-virtualized)
- Memoization (React.memo, useMemo, useCallback)
- Code splitting
- Lazy loading

30-Second Answer Framework:
"I'd implement virtual scrolling with react-window, memoize expensive calculations, and use React.memo for component optimization."

Instant Feedback: Mention specific performance metrics you'd measure (render time, memory usage) to show analytical thinking.

Question 4: Problem Solving

"Write a function that finds the longest common subsequence between two strings."

Key Points to Address:
- Dynamic programming approach
- Time/space complexity analysis
- Edge cases (empty strings, no common subsequence)
- Clean, readable code

30-Second Answer Framework:
"I'll use dynamic programming with a 2D table, comparing characters and building the solution bottom-up. Time complexity O(m*n), space O(m*n)."

Instant Feedback: Walk through the algorithm step-by-step with a small example to show clear communication skills.

Question 5: Architecture & Scalability

"How would you handle state management in a large React application with multiple teams?"

Key Points to Address:
- State management libraries (Redux, Zustand, Context API)
- Code organization and team boundaries
- Performance implications
- Testing strategies

30-Second Answer Framework:
"I'd use Redux Toolkit with feature-based slices, implement team-specific modules, and use RTK Query for server state management."

Instant Feedback: Discuss how you'd handle state sharing between teams and conflict resolution to show enterprise experience.

Question 6: Behavioral & Leadership

"Tell me about a time you had to learn a new technology quickly for a project deadline."

Key Points to Address:
- Specific example with context
- Learning strategy and resources used
- Challenges faced and how you overcame them
- Results and impact

30-Second Answer Framework:
"I learned GraphQL in 3 days for a client project by building a small prototype, reading official docs, and pairing with a senior developer. Delivered on time and improved API efficiency by 40%."

Instant Feedback: Quantify the impact and mention how you'd approach similar situations in the future to show growth mindset.
