Quality is more important than quantity in engineering, so a mediocre hire can be a net negative. In so many ways: - consuming time and attention from people who help them - time spend checking and fixing their work - additional maintenance costs from poorly thought out solutions - time spent reproducing and fixing bugs - lowering morale of better engineers - creating whatever the opposite of “a culture of excellence” is - consuming management time in performance management - inability to interview or saying “yes” to even worse hires
