how many things did you learn by seeing / being taught the solution and how many did you re-invent as you're basically asked to do at an interview? To give maybe a bad example, I don't know how to do a quicksort. I've written it maybe twice in my life by either being taught by a teacher or by looking it up on wikipedia. I didn't have to think of the solution on the spot. I'm not saying I can't think of solutions but still, the majority of my knowledge comes from having been taught and then using that taught knowledge over and over, not from re-invention. Note I agree we have the same goals to hire people that can do the work not people whose friends can do the work but I'm not convinced that the typical interview puzzles (find the longest segment of an array that contain 3 values) has anything to do with actual work skills. Maybe it would be better with more typical tasks? If the person claims to be back end engineer ask them to write a query to select all people between the ages of 30 and 35 in Nebraska? Maybe if they are front end ask them to implement a select/option UI?
