You will dramatically improve your chances of getting past a technical interview, landing that dream job and earning more money.
However without a grasp of the deeper fundamentals you will hit quite a few head scratch-y issues, introduce bugs, find it hard to read and understand framework and library code and won’t be considered a senior developer.
What are you going to learn?
Why an interview format?
I find that it's only when i'm facing an upcoming interview that I get into gear and really make sure I have a deep understanding of what I claim to know.
I might know the best practice for how to solve a problem, but do I know why?
Also it's FUN, what's more satisfying than learning something, then passing a test!
