> looked for general knowledge over specific knowledge This is one commonly thrown BS regarding interviews. At the end of the day it is all about one-dimensional usual algorithmic questions. Regarding LRU cache, I think this is one of less crazy interview questions. In one phone interview, I had to solve a DP problem, code it perfectly and pass all the test-cases on HackerRank in less than twenty minutes. I am not certain how many developers out there can pass such interviews without months of preparation in such situations. Tech interviews are basically programming contests. I am not against programming contests or algorithmic questions. But it seems the interview questions are getting crazier day by day.
