Summary

Had a hiring manager interview that was supposed to be mostly behavioral, then got blindsided by a live coding problem. Solved it fine but barely said a word while doing it, and two days later got the rejection email.

Suggested Approach

Start by clarifying the problem and constraints, then discuss a brute-force approach before optimizing. Implement the solution while explaining your thought process, and finally analyze time and space complexity, considering trade-offs.

Pro tip: While coding, verbalize your reasoning and edge cases; this shows collaboration and thoroughness. Also, after implementing, test with a few examples to catch bugs early.

1. Understand and Clarify

Ask clarifying questions to confirm input/output formats, constraints, and edge cases. Restate the problem in your own words to ensure alignment.

2. Discuss Approaches

Propose a brute-force solution first, then suggest optimizations. Explain the trade-offs between different approaches in terms of time and space.

3. Implement and Explain

Write clean, modular code while explaining each step. Use meaningful variable names and handle edge cases as you go.

4. Test and Debug

Walk through your code with a few test cases, including edge cases. If you find a bug, debug it methodically and explain your fix.

5. Analyze Complexity

State the time and space complexity of your solution, justifying each. Discuss potential improvements or trade-offs if relevant.

Key Points to Mention

  • Clarify constraints and edge cases before coding.
  • Start with a brute-force solution and then optimize.
  • Explain your thought process while coding.
  • Test with examples, including edge cases.
  • Analyze time and space complexity accurately.
  • Discuss trade-offs between different approaches.
