If someone can memorise how a dictionary and an array work, why would they have trouble quickly understanding how a hash table works for example? To me, coding for years and never coming across or being curious about understanding hash tables when they're applicable in so many places and not hard to understand is a bad sign. I don't care about more esoteric data structures but linked lists, hash tables, arrays and binary trees should be basic knowledge.
