I do get that, and I'll be more sympathetic to hiring managers who want to see open-source code than I have been in other comments.

( Active job hunting tends to make one grumpy. Take home programming assignments are a current sore spot for me. )

It's a recent job posting that said "Requirement: OSS contributions" that seemed over the top. Maybe it's no less troubling than "Requirement: SQL expertise" - after all, we're all 'discriminated' against to some degree by not having experience in everything a future employer might want.

With the SQL requirement, however, there's an obvious drag on a project if they bring in a new hire who has no SQL knowledge. If a team working on OSS hires someone with no OSS experience - is that going to mean they can't contribute right away?
