Alex Hu

Alex Hu is a software engineer and technical author known for his work on system design and algorithm interview preparation. Coding Interview Patterns presents a curated set of the repeated structural patterns — two-pointers, sliding window, backtracking, dynamic programming — that recur in technical interviews.

Hu, who has mentored hundreds of engineers through the Silicon Valley hiring process, writes for early-career software developers facing the algorithmic gauntlet. His books have become widely recommended references in the coding-interview genre, alongside the System Design Interview series that he also contributed to.
