What does “good” mean? You can get a high mileage out of learning how DP and greedy algorithms work and having wide array (hah) of data structures.

  My definition of "good" in this context is being able to solve a Leetcoed medium in 25-30 minutes on average.

    I expected 10-15 minutes for mediums. I was at that point a year ago when I was prepping for AWS and I am not some genius or anything special. It’s probably even easier to just write anki cards with the solutions and memoize them (pun intended).

      That's frankly never going to be possible for someone like me. 10-15 minutes just sounds crazy. I'm lucky if I'm able to understand any problem well enough to get a brute force solution in under an hour. The O(n) or O(log n) they actually want, that's just going to be pure luck that I recognize one of the patterns that will let you apply that. The time constraints just make this whole thing exacerbating.
