I agree. I have noticed there are a lot of people who really struggle when they are put out of their comfort zones of X framework in Y language working on mostly the same or similar code bases. There are lots of companies that just need a guy who knows Spring design patterns or something, and they shouldn’t be giving tough algorithmic challenges, but at certain tech companies paying highly for people to work on very diverse sets of problems, many of which are technically complicated, it makes complete sense to prefer people with very strong fundamentals.
