I loved working with the Collections staff and volunteers--there were always enriching projects to work on, and the group environment was very caring and friendly.
What I wish was different
I do wish there were more interactions with exhibits, but the projects behind-the-scenes were incredibly wide-ranging and educational.
Advice
Prepare yourself for public speaking and networking! It's not a docent job, but there's a lot of interpersonal wrangling you may have to do. Also, don't apply if you're not a fan of database updating.
