Asking candidates – or even tracking – how they applied to your position may be giving you a misleading picture.
A couple of weeks ago, CareerXroads released the results of a study showing the sources of external hires:

Now, most recruiters will tell you that they’ve long known that the best source of new hires are referrals, so it’s not surprising to see them at the top of the list. However, given the long-heralded demise of job boards, and the long-heralded power of social media for recruiting, it’s surprising to see the former coming in second while the latter is a bit of a blip.
The first thing we need to acknowledge is that the sample size here was only 36 respondents – not nearly enough to know how accurate the results are.
However, what may be more important is that recruiting is hardly ever this simple or one-dimensional.
How many touchpoints does it take to generate an applicant? How many to generate a hire?
99.9%, when organizations are tracking where a new hire came from, they’re (a) asking candidates to specify how they came to apply in the first place and (b) looking only at the most proximate cause.
And sometimes it really is that simple: Candidate A is in the market for a new job, so s/he goes online and looks for opportunities, sends applications to anything that looks promising, and then hopes s/he will get an interview.
But most of the time it’s much more complicated than that. For example, Recruiter Sally needs to hire a senior manager. She posts the job on the company website, puts feelers out on LinkedIn, calls a few contacts in the industry, and sends an email to internal employees to ask for referrals. She includes the link to the company website posting in emails to potential referrers and her LinkedIn status, and tells internal employees to direct their contacts to the company posting but to make a note on their covering note that they’ve been referred by someone.
She eventually makes a hire via a contact on LinkedIn, who has applied via the company website after having been referred by a former employee.
When the new hire is asked “How did you apply for this job?”, s/he says “I applied on the company website…” – when in fact the ‘source’ of this hire was a combination of social media (LinkedIn), referrals (via the LinkedIn contact and employee alumni network), recruiter initiated (getting the buzz going), and the company website (which facilitated processing).
It may be time to stop thinking about ‘single source of hire’ and start thinking about ‘engagement process required to make a great hire’.
