This is why the tech interview is still an unsolved problem (for non-tech ppl).
How does a non-tech role sift through the 32 devs who did 10YOE flipping bools vs. the 3 that built the entire system? They'd look similar on paper and in superficial conversation.
This is the plague of hiring senior engineers, and one of the reasons we needed a new code test/challenge to get fewer bool flippers in our senior engineer hiring process. If you make them do something complicated/complex you get a lot more signal than if the test is bool flipping/a simple project from scratch
