We know. You created a stellar job posting, sourced and interviewed, did all the right things. You took your time with the process and the perfect candidate emerged, consensus was reached and you made the hire. Flash forward a few months and the feedback is flowing in from the company. The new guy sucks. Hiring misses happen to the best of companies, and hiring managers, more often than we care to admit. So what do you do when it looks like you might have missed on a hire?  Do you try and fix the problem, or do you make the call to fire fast?
