Identify a recruiter that understands your WHY. Once you have a recruitment partner, engage them by retaining them, let them be part of your team, albeit outsourced. Involve them in your strategy planning to manage your people growth as well as fill the inevitable holes that will appear in your team.
Don’t spread your risk by engaging multiple recruiters, it doesn’t work. Your recruitment partner has access to all of the talent nowadays, through LinkedIn and Job Board databases. Engaging multiple recruiters dilutes your message as candidates are often contacted by multiple recruiters which reflects poorly on your brand
