Here is an alternative funnel, with what I hope is a better sense of proportion and scale. Your comments helped me a lot.
Here's the idea behind the funnel. You have ads that help your candidates screen themselves in or out. Of course, there are always some people who don't screen themselves out, so you have many people at the top of the funnel. That's why I tried to make the filter a loose filter at the top. Do those filter lines look loose to you?
Next, the candidates send you a resume. Those filter lines look pretty loose, too.
Now, you have your resume screening filter. I still believe in a pretty loose filter here, but your mileage will vary. I explain more in Hiring Geeks That Fit how to make a looser or tighter filter. After you review resumes, you will phone screen the ones you like. That involves yet another filter.
The resumes that make it past your phone screen filter are candidates for in-person interviews. And, of those, the ones that make it past the interviews are the ones that you can make and extend an offer to.
What do you think of this image? I'm looking forward to your comments.
