Ask HN: How do people use social networks to find jobs out of school?

I am gathering information about how social networks can help new graduates to find job in 2021. I have been in the industry for a while and it does not appear that social networks played any tangible role in my employment, including the ones that are geared toward professionals. So the question I have is if anyone has any success story using LinkedIn, Facebook, Twitter, and similar platforms to find a job out of grad school?
