To me, recruiting is two problems: outreach and qualification. You're asking about outreach. How we did outreach is a whole 'nother blog post, and one I'm bound to write soon. What surprised me about recruiting was how much more important qualification is than outreach. Without good qualification, it almost doesn't matter how good your outreach is, because you're filtering for the same highly visible easily accessibl…
Maybe I wasn't clear with my question. Say the company indicates it is hiring and gets 100 interested people. How do you filter them down to serious applicants without looking at resumes? I would argue that isn't so much outreach as it is qualification, as the people are already interested. Maybe my premise of 100 candidates is incorrect based on how you did outreach?
How do we figure out which ones are serious? We talk to them, usually give them homework, and then give them work-sample tests. This is not particularly expensive for us, and gives us repeatable, relevant, apples-to-apples metrics on how qualified they are to do the work. This is, as Tom insists, surprisingly easy for us. (Not to say it's easy, but nothing about hiring is easy.)
