I get a lot of recruiters that are trying to fill positions at defense contractors. So right away I know two things: - I'm not interested - They aren't at liberty to talk about the technical details So I always respond with something like: > Oh yeah, I'm pretty decent at {language}. But I want to keep growing, so I'm really not interested in writing {very old version of language}. Can you tell me what version they're using? I figure it's a good balance between "screw off" and bothering with a phone call that won't be fruitful for either of us. It keeps me in their rolodex (in my experience, recruiters have a very high turnover rate--so who knows who they'll be recruiting for tomorrow). Also, I like to imagine that some poor engineer is trying to convince the machine to let him upgrade, and maybe I can help them out, whoever they are, by making the old version seem like a recruiting hazard.
