Summary

Interviewed for a senior full stack role at a FAANG company in the EU. The loop had three rounds and the virtual UI coding round went pretty badly. Two weeks out from the in-office rounds and genuinely unsure if they'll bother flying me in after that performance.

Questions Asked (1)

Q1

Four JavaScript puzzle-style coding problems in a virtual UI round, expected to be React-focused but turned out to be closer to algorithmic JS challenges.

Suggested Approach

Start by clarifying the problem requirements and edge cases, then outline your approach before coding. Use clear variable names and modular functions, and test with examples. If stuck, communicate your thought process and consider multiple solutions, discussing trade-offs.

Pro tip: Demonstrate strong fundamentals by writing clean, efficient code and explaining your reasoning. Show adaptability by acknowledging the shift from React to algorithmic problems and relating them to real-world scenarios.

1. Understand the Problem

Ask clarifying questions to ensure you understand inputs, outputs, and constraints. Confirm edge cases and expected behavior.

2. Plan Your Approach

Outline a step-by-step plan, considering multiple algorithms and their time/space complexity. Choose the most efficient one and explain why.

3. Implement the Solution

Write clean, modular code with meaningful names. Comment on key steps and handle edge cases.

4. Test and Debug

Walk through your code with sample inputs, including edge cases. Fix any issues and verify correctness.

5. Review and Optimize

Discuss potential optimizations and trade-offs. If time permits, refactor for readability or performance.

Key Points to Mention

  • Time and space complexity analysis
  • Edge cases and input validation
  • Modular and readable code
  • Testing with examples
  • Trade-offs between different solutions
  • Communication of thought process
