I don’t think it matters very much if you’re (roughly) within the ‘acceptable’ window for whatever social environment it is in which you find yourself.
I tend to eat in a pretty messy way
Do you get food on your clothes or parts of your body other than your mouth (or immediately around it) or hands? Do you get food on the table/surface at which you’re eating? Do you get food on other nearby people? If not, you’re almost certainly fine, either “in software” or any other field. You might suffer tho in fields with a relatively larger proportion of upper or upper-middle class people, but you probably already know now whether you even want to enter the relevant ‘tournaments’ to earn an opportunity to enter those positions (and I’m guessing you don’t). If you did tho, an etiquette class might be worthwhile.
