Passing unittests alone are irrelevant. There are other relevant metrics too. [..] They had no clue how to calculate time complexity. No clue why provided unit tests were not enough and etc. [..] This part makes the impression that you lack the pracmatic understanding of real world-coding. Testing to much, focusing on unimportant things, building to big and wasting to much time for worthless things. In coding there are usually two type of people: tinkerer who get things done fast and dirty, and academics who slowly build shiny ivory-towers. Both have their legit space, but not every job fits both of them equal good.
