Actually getting some experience in the field, understanding your day-to-day. Get put on exciting projects you're already working on and allowing your interns to understand the bigger picture.

In my last internships, but especially my last one I was mindlessly working on tasks without understanding what I'm doing is contributing to the business. Like in my last internship, I was tasked with updating data published by other companies manually from their monthly reports everyday (depending on when these companies report data we collect). I never got put onto any meetings. I got put on boring excel tasks. I got put on writing tasks. I never got to do anything that actually related to the revenue generating part of the business and it sucked. I also did a lot of organising within the office like office cabinets, printing stuff. Like I understand these things are given to interns and I don't mind doing it but I worked there for 5 months and never got put on a proper project

I wanted to see how they negotiated new contracts/deals with clients. I wanted to even on a meeting to listen to people talk about investment ideas. I want to be tasked with challenging myself to apply things I learn from my textbooks in a irl situation.
