Get Computer Science Crash Course with Imposter's Handbook
I just finished reading Rob Connery's book Imposter's Handbook. It's a very good high-level overview of Computer Science concepts that you may not encounter in everyday job. It is also a good guidance for "what I should know".
If you do not have CS degree I recommend you to check out this book. You can skip chapters about concepts that you are familiar with. If something is new to you - this book will provide you nice introduction to the topic, which you can later on dive in on your own.
If you do have CS degree, I still recommend you to at least check out what's there. I'm sure you will learn something, or at least refresh your knowledge.
