> I would say, specifically in the US where this type of question is asked, it is negligible compared to a dev's yearly salary. What one should consider is the time spent interviewing all candidates versus the cost of making a bad hire and doing it all over again. The only thing you're limiting when interviewing fewer people is the short-term cost of "hours spent doing interviews". That's a myopic metric. You are right, most of the cost is in the bad hire. > For one, noise is subjective. And in filtering out the noise, you're filtering out outliers - both good and bad. Even assuming you're right, that would only mainly apply to juniors. True and true. A bad hire is extremely costly.
