Back when I was a career coaching, I used to run a popular workshop on salary negotiation for the local job search meetup. It broke down salary negotiation into a set of 6 skills you could practice such as timing your offers, deferring salary negotiation, overcoming objections etc.
There’s another good post on salary negotiation in an ETG context here: https://www.lesswrong.com/posts/Z6dmoLyfBdmo6HEss/maximizing-your-donations-via-a-job

The great thing about this was that after the initial presentation, job seekers could practice the skills with each other meaning I wasn’t the bottleneck. Presentation is here: https://www.evernote.com/shard/s8/sh/d45a92cc-a8d0-4b3b-adf5-53b53e1efbc6/a423ecc18c4d0a386b5fe1d2284680f7
I could see a similar idea of a practice group working for EAs.
