I don't know if this is sarcasm or not, but in case you're serious. The fact that you feel the need to approach this like you're a gladiator preparing for mortal combat in the arena of the mind, is really not OK. Our industry's interviews shouldn't be like this

I majored in computer engineering and skipped algorithms so it was pretty intense studying for a couple of months before I felt comfortable. Overall I really enjoyed learning it but I made it through so many successful years of software engineering without learning it that I don’t think it’s relevant to most people. Even now I write an O(n) algorithm to merge sorted lists and people comment on my PR just tell me to throw everything in an array and use the sort function.
