I got my second job with a program listing.
(In the really old days we printed stuff out with dot-matrix printers on this fan-fold stuff, sometimes with alternating strips, and holes down the side. It even made BASIC look important).
It was advertised as a “starting position for a graduate in Computer Science”. I walked in, without a degree, slapped down the listing and said “I can understand and maintain code like this — see the comments I added as I worked on it.”.
I’d been working for a little company that customised accounting software — the mining company that hired me needed someone to maintain their accounting and warehouse systems.
I didn’t have a degree but I had proof I wouldn’t run screaming from a ton of horrible code.
