I got hired by a local company exactly for my experience with running linux servers at home and in a semi-professional capacity. They had hired someone with perfect credentials from university with several masters degrees, but they had to let him go after half a year because he did not fit in to their linux environment that has been operating since the 90s. I had no formal education, but many years with tinkering, self-hosting and operating linux machines for a small number of customers, and they could not hire me fast enough. They told me that it is really hard to come by people with this mix of experiences, everything is in the clouds these days.
