Job shadowing/interning at a Law office?

I’m a current Junior and my mother’s friend has offered to get me an internship at a local law office over the summer, would something like that look good on an application?

yes!

On a college application? It will look like a job or a volunteer position.

yes…colleges like to see you do something productive over the summer.

I’m going to be interning at a law firm but I’m going to be doing tech stuff like creating a database, creating infographics, filming/editing videos, taking pictures, graphic design, etc… would this still look good if I’m going into STEM since it’s kinda related?

It is more that you are doing something than what you are doing. You could be a camp counselor or work at mcdonalds or babysitting your siblings or whatever.
