> DP or graph approaches I don't use either in my day-to-day. I also have memory issues around just memorizing these things. I can probably do it if I can look

  Again, it’s not really about “just” memorizing them, it’s about internalizing how they work to the point where they are second nature. Like being able to apply calculus to everyday life, once you have internalized it, it changes how you think about things and analyze problems. Learning calculus through memorization will not help with that.

    > internalizing how they work And how long do you expect that to take? Do you think I haven't tried doing that before? It just doesn't register unless i'm literally doing it every day. And with so many algorithms out there there's not enough time to internalize all that. I don't have that kind of memory everyone else seems to have.

      > And with so many algorithms out there Their point is that this is wrong. They're saying there's a few underlying principles that apply to most of these, and those are what you have to internalize.

        Yeah, a few concepts like hashing, "divide and conquer" and dynamic programming is enough to solve most problems. If you understand and know how to use those and a few more well you easily ace interview questions because those are the building blocks for almost all useful simple algorithms that you get asked about in interviews.

  If you think these things are about rote memorization, you’re doing them very wrong.
