I don't think this book or any books for that matter are particularly useful for interviews unless you want to learn the extreme basics. However, if you are trying to learn the basics, I'm not sure that this book or EPI, etc. is enough to be prepared for a real interview.
The best way really is to grind Leetcode, unfortunately, and using ChatGPT to ask questions and explain answers or topics. ChatGPT is very good at explaining well-defined things like CS topics and LC answers in my opinion. It most likely slurped the contents of this book and you can ask it questions directly so I think that's probably the way I will do it in the future.
In addition, the book doesn't seem to cover systems design which is an extremely critical part of the interview process for L4 and above.
