I mean if you are using interns as a way to find future employees, I'd check out the code they wrote for the best metric.
Most of them are probably hungry for a high paying tech job, and will tell you they want an offer / want to work with you. Even if to just get another offer for some bargaining power. It's probably worth asking them questions about how easy it was to ramp up and such if you are in a position where you can improve those systems.
Check out the code, is it well written? Modular? Documented? Did they go through the proper steps in your sprints / documentation? Ask their mentors if they asked questions when blocked, etc.
If they worked hard, had a good attitude / could get along with the team and wrote good code (remember they are new to coding most likely) - and you think they have a lot of potential than consider giving them an offer.
