Meta: below is a very non-generous view of 80k one-on-one career advising (kinda bitter to be honest). I will probably be raising points that the 80k team thought about over the years and decided against for a good reason but I have not seen them publicly discussed. I will be very happy to be wrong about this.
To sum up: 80k one-on-one career advising has a small negative effect on the world
Why
I have an impression that 80k accepted a long time ago that that wait time will just have to be pretty long. Here is a bunch of ideas to shorten the wait time that I don't think were attempted historically:
The advising page also says that
It costs hundreds of dollars to provide this service to a single person.
It is not clear to me that the price of having in-house career advisors is justified. I think there are a lot of people (like a hundred) in the community who could gladly volunteer a couple of hours per month to do career advising and would be super excited about the opportunity to help out and share their knowledge and connections with the newcomers.
I believe a structure that has a small experienced 80k career advisor team (2-4 people) managing a community of vetted experienced EA volunteers would be a much more promising way to go. Or alternatively have the community fully self-organise for this project.
Thank you for your thoughtful replies, Michelle.
