I think it depends a lot on the company. If their oss project doesn't get much love and someone is trying to force their way in, I don't think it will work out well. But Posthog for example have oss in their DNA and I was using their product, communicating with their excellent support and fixed a tiny bug in their Ruby SDK. A while later they reached out with a job opportunity. It didn't work out in the end but it was a fantastic experience!
