Back in 1998 or 2000 (I don't remember the exact year), I did RHCE and IT networking certificate. It landed my first corporate gig as I was the only person who knew Linux. In addition, I was the first hire who started replacing traditional Unix servers with RHEL. So, yes, it did help me despite not having a college degree. I am very thankful to Linux and FLOSS for paying all my bills over the years.
