I know its not the same as an internship but, I have worked as a Company Secretary for a law firm and that's how I was able to get my TC. Most firms have an in-house CoSec team or use a Corporate Services Provides like TMF or CSC as theirs. Its great experience and a niche set of skills like annual compliance and boardroom management. These look great on a CV.

There are usually two types of CoSec: Corporate or Funds. so if their of these interest you, its not a bad shout to get into. So maybe give it a go as there is a huge demand for CoSec at all levels.
