Technically: Yes. The "fixed" PDF is a functional, high-quality digital copy of the book. Professionally: No. If you are interviewing for a six-figure role ($200k+), you can afford the $40 book. Furthermore, the act of buying the book gives you access to the author's errata page (list of mistakes fixed post-printing), which the PDF does not include.
The Secret "Fixed" Update: In 2024, Alex Xu released a supplementary chapter on LLM/RAG design (How to build a ChatGPT-like system). This chapter is NOT in any "Github fixed" PDF from 2022/2023. It is only available via the ByteByteGo paid subscription. If you study the old PDF, you will miss the most important interview topic of 2025.
