I worked as a paralegal for a while.
At the low end, you are basically sitting in a small room reviewing tons of documents (contracts, emails, file attachments, images, etc) and adding details about each one to a database.
It’s pretty easy work if you are attentive to details and don’t mind typing for hours on end.
I got tired of typing for hours on end so that was the extent of my experience, but I know that some people work as a paralegal for 40 years. Obviously, there are many different activities that would be peripheral to the legal process and I’m sure there are a variety of opportunities if you stick around the system.
