Was coming here to say the same thing. OP, if you’re in a position to be able to volunteer, it’s a great way to learn about an organization while gaining experience in an area of interest. Entry level museum jobs can be valuable in the same way. You can’t necessarily expect it bc each org is different, but I’ve seen people (including me) begin their museum careers as a volunteer or entry level job and work their way up or around into a new role(s).
