On interview, ask: "Does this company participate in open source projects/has a few?". If no, run away. If yes, it's a pretty big chance to get a nice job. (don't know if this works)

I doubt that will have anything to do with your possible experience with the company.

I agree with @monkeyboy. I fail to see how something like that woule influence as a whole.

"What? 90% of startups and small companies don't do that but I still have to get a job?" *confused pikachu*

Just because their code isn't open source doesn't mean it's a bad place to be. My company doesn't open source anything, as is their right as they've put a lot of money into development, but I quite like it there anyway 🤔 the company I am working with for a school project made us sign an IPR, and I quite like that place as well even though I no longer own my own code.

This everthing must be open source trend is getting out of hand

has anyone seen the tags?
