Are you insisting that you're not qualified for the position on the basis of that Linux / Unix distinction alone ?

If so, that's really really sad. Even more so if you thought "Unix-like" genuinely disqualifies you because it's not strictly "Unix" !

You need to be more confident about your skills. Most interns don't know how POSIX relates to UNIX and Linux like you do, if they are even familiar with the word !

Look, I'm a former Facebook production engineer. I won't exactly reveal a secret by saying that FB is wholly Linux based. It's not a bank with legacy commercial Unix systems, and you were of course right about the 1970s engineers comment.

Positions requiring expertise with a specific brand of Unix are less and less common, and these would always mention the flavor they're after anyway (mostly Solaris, possibly some AIX/HP-UX).

One more general piece of advice : let others decide that you're not qualified for, don't self-censor before you even get a chance to fight.

Pure Unix is not even thought to CS students anymore. Looking for Unix experience for internships is utterly pointless. The Recruiter should have been happy that there was Linux experience, because even that is not a given.
