Not totally clear what you're asking. Would the slack group be just for job seekers, or would it have hiring staff in there too? Would it be a separate slack server per company, or literally one server for everyone?

I was thinking one server and just for job seekers. Like a support group for people looking for tech jobs.

Maybe there could be channels per role/level, like #backend-senior, #ml-junior. So you could discuss hiring process and get tips from people looking for similar roles.

If youre a job seeker and would be interested to join a slack, drop a comment here or email me: [email protected]

I know you've mentioned Slack multiple times, but please for the love of all things holy don't use a closed system that deletes messages and isn't easily discoverable via search engines. Zulip has built-in support for a providing SEO renders of the messages and I'd imagine one could easily self-host it in Oracle Cloud's free tier, or apply through their sponsorship program https://zulip.com/plans/#cloud-sponsorships

https://zulip.com/help/public-access-option and https://zulip.com/help/moderating-open-organizations are relevant

Zulips topics are also just plain better than slack and discord threads.

Honestly, I would rather join an IRC server for people seeking tech jobs.
