Talking a good fight
You need to recruit. A CV hits your desk. The candidate looks to be everything you are looking for. You go through the interview process. The candidate performs well, looks a really good fit. You make an offer to the candidate they accept and agree to come to work for you.
A few weeks go by and the new employee is struggling to match your expectations. You sit down with the employee and talk through the issues and how you can help them. The employee accepts the help, promises to try harder. Sometime elapses, the employee has tried but still not achieving the required targets. You are in a quandary. Can you get the employee to the necessary standard or do you to let the employee go and start the recruitment process again?
The question is why was the CV so good in the first place? Had the candidate embellished their achievements and experience? Had they taken the credit for someone else’s success? Maybe the candidate believed they could do the job? Maybe, the problem lies within your organisation, your training?
Just because someone has spent some time at company A or company B does not guarantee their proficiency. The only real way to know how good the potential employee is, is to give them a chance.
