If you get your (initial) training from a neutral-ish impact organisation, like some management consulting or tech companies, and then move on to a high impact job, you can add value right away with less ‘training costs’ for the high impact org = more impact.
All else equal, an EA org with staff with 1-3 years (non-EA) job experience can achieve more impact quicker than one with partly inexperienced staff.
That said, some things such as good epistemics or high moral integrity may be easier to learn at EA orgs (though they can definitely also be learned elsewhere).
