How do you propose filtering the candidates? The only way to know for sure how they perform is to actually hire them and see how they perform after some amount of time. Since you will be firing a majority of people this causes a culture of fear. Interviews are far too unreliable for filtering candidates like you are proposing.
Exactly. If you hire 4 it is likely that 1 will be very good and 2 average and 1 bad. If you hire 1 you probably hired the one who knows how sell himself/herself.
