Of course, and that right there is luck of the draw. Didn't list the specific thing I need help with? Might not make it to the list of 20 I look at. Not because I wouldn't hire someone for not listing it, or demonstrating they can Lear quickly but jiet be cause I have a limited amount of time.
Or it's look at schools. See if any of the companies pop out and they spent some time there. Obvious exact skills match. The resume isn't too long. Whatever I can get in a 30 second skim.
