The best book for preparing for programming job interviews

This post is for programmers looking to level themselves up for better career prospects. I am recommending a book that has helped me to do the same for myself.

I’m a self-taught programmer who had to learn on the job from the beginning. It wasn’t easy — facing problems that I didn’t have any context of. I started off with Ruby on Rails, then moved to Node.js. I learnt best practices along the way. Time to time, I looked back at my older code and was overwhelmed with shock and horror at how bad the code was.
