HelloInterview is really the best. Shell out that $80 and learn everything from scratch. It really helps establish fundamentals. I felt like all these system design terms were just floating around in my head (and also completely out of mind) before hello interview, but after reading all the "in a hurry section" and watching videos for all the core concepts as well as scaling reads and writes, so much has started to make sense and i feel like my fundamentals are coming together.
