Made this over the summer when I was job hunting. Even now it's incredibly useful and easy to reference whenever I forget something I shouldn't. I figured I'd post it here for you all in case anyone wanted to use it.

Feel free to request new information/sections (or make a PR yourself ;)) if there's something missing from it that you'd like to see.

Hopefully it can help some of you out!
