You probably don’t want to hire the first person you interview, since you don’t know what the baseline is. You don’t want to hire the last person either: you almost certainly have passed on your best candidate at this point. So the optimal strategy involves interviewing and rejecting the first few candidates no matter how good they are: just to set up the baseline first and then hiring the best you’ve seen so far after. This optimal point turns out to be 1/e or about 37%. Reject 37% of the applicants, and then hire the next one better than anyone you’ve seen so far. via Hacker Noon
