Hire slow, fire fast has long been advice I have given.
Take your time hiring new employees. Know what you’re getting.
If things turn bad – you see attitude problems, customer relationship trouble, skills that are lacking, and other broad issues – fire them. The faster you get rid of bad apples, the better.
Avoiding the problem people is the best approach.
Pre-interview tools can help you weed out those with small chances of making positive contributions.
