Pretty much none that I'm aware of. My brother is an actual engineer. They get hired on past relevant experience and simple interview. Of course he also needs the relevant credentials and professional membership so there is that... you can't keep those if you mess up and you won't get recommendations if you are an ahole. A lot of my friends are doctors. If you are qualified and want the position it's yours. Demand > supply very much so. Hospitality is as cut-throat as always, everyone is welcome to try - it's up to you to survive. Though I guess the first few trial shifts are the most similar to programming in that way but it's still very much "can you do the job" not "can you remember this esoteric thing you might have done once in college but otherwise not touched in a decade". So yeah. Programming stands alone in this sort of gauntlet hiring system in my experience. Other fields are happy to take past experience and recommendations as they are instead of devising some sort of "test". I would say outside of programming there is a bit more of the personality test sort of things though - especially big corporates, you could probably screw one up badly enough for HR to block you.
