Probably not, you can have a career never using linked lists . The problem is that it's such a fundamental CS concept it's going to be hard to pass interviews without that knowledge if you were starting from a junior position. To me it's not a paradigm. It's how data is stored and represented in memory. Where such issues become problems in larger projects is when you have a lead that doesn't know what B-trees are and they need to optimize database access. Or that person is loud and influential and derails every technical conversation because it's way over their head.
