Vanquish whiteboard interview puzzles with test-driven development

This article reveals a strategic approach to conquering whiteboard interviews by transforming the typical high-pressure coding challenge into an opportunity to showcase problem-solving skills. By introducing a systematic four-step process of explaining, testing, coding, and debugging, the author provides engineers with a method to not just solve algorithmic puzzles, but to "impress the interviewer" and demonstrate professional problem-solving techniques. The guide offers a practical framework that shifts the focus from merely solving the puzzle to effectively communicating technical thinking and methodically addressing coding challenges.
