Best non-banking internships to get into Trading

I’m looking at internships as a trader at a bank or one of the top prop firms, but there’s only so many of those to go around and I’d like to hedge my bets by applying to a few non-trading roles.

I’m wondering what internships would impress trading firms the most for when I apply to them next year, in case I don’t get in this time around. Looking at a few engineering roles, though they’re not my favourite; what else could I apply to?
