All recruitment carries a certain degree of risk; it’s often how this is managed that dictates the outcome and success. No matter how many tests are carried out checks are made, you can never be totally sure that a candidate is going to work out. In fact, if you are 80% sure, then you are doing well.
So, there is an element or risk; either get used to it or don’t recruit in the first place.
Some employers seem to put up barriers to recruit, these are either mandated by the company in terms of procedure or allowed by the company in terms of fear. No hiring or recruitment manager should be scared about recruiting someone; otherwise why are they in that position to being with?
If decisions can’t be made quickly and efficiently, especially in today’s candidate driven market, then you are either doing a disservice to the candidates or your company. Ultimately, there is a vacancy for a reason and all the time the role is left unfilled will result in a loss of productivity or lack of sales.
So, try to keep it simple (2 or 3 stages), understand candidate motivations and market dynamics (salary benchmarks) and trust your instincts.
