If despite your best and most concerted efforts, the person still refuses, use your networking skills and ask the person to give you a few good references for people who could probably fit the job. This saves time for you to start the process from the beginning and also keep this person within your networking system. Also, always keep in touch – while the passive candidate may not be available today, but whenever they are, you should be the first contact they reach out to. Remember that this is a marathon and not a sprint and while most of the hiring is need-based, in young companies, you should always be open to get the good guys in.
Today’s employers are better placed to source and recruit these ‘elusive unicorns’ given that they have social media and varied technologies at their disposal. Getting to these persons is now a cake-walk or as we have said – as fluid and lucid as the movement of a slow dance!
