Too late.
The trade off is training. If there's no meaningful program - it's usury. Perhaps you haven't been actively engaged in the trades, but there aren't enough appliants to go around.
Shops with high turnover are a dead end. If you only see the business end of a broom and an unending supply of sawdust - walk. Look around - is it one or two regulars over 50 and a rotation of twenty somethings? Where did the rest go?
Again, you may not have recent experience in a larger concern. More likely is the invasive surveillance of when you arrived, the number of steps walked and your online presence.
If the terms and conditions of an internship include "at will", NDA or non-compete clauses - WALK.
The guy who jumps in and doesn't get paid is a tool.
