The only way to maintain privacy and job hunt is through a strong social network, and I’m not talking Facebook. When you have enough contacts/friends in a sector, you can ask around.

When you are job hunting you don’t want privacy, you want your info (i.e. your cv) as widely distributed and known as possible. Create a dedicated gmail account.

The key is to keep your professional internet profile andnl your private digital life separated.

You can’t job hunt privately, the whole point is to sell your services to a public market.

LinkedIn is a crime against humanity.

Unless you specifically look for jobs at politically oriented organisations (eg companies that pander to the privacy-conscious crowd, non-profits, etc), I just keep my professional life and my political life separate. I’m sure most people just have a “work profile” for job stuff and keep their personal life private.

Hack into their system and upload your resume.

Instead of doing LinkedIn, look at individual companies’ web pages for their careers section. Make a temp email, look at LinkedIn or other job sites to see who’s hiring, then look at those companies’ web pages.

Become self-employed, I guess?

Find a company you want to work for, hack into their accounts and add yourself to their payroll.

I go years between linkedin logins. Every time I log in to look at a profile or whatnot, I get bombarded with spam for months.

Indeed doesn’t take any personal info or require an account.

I’ve been using LinkedIn with addy.io’s aliases a couple years without issue, I can’t say if that somehow makes your profile less promoted, I can only say that I’ve been receiving a few proposals here and there, don’t have a lot of experience, so I think it’s reasonable I don’t get swamped in them.
To be fair though, the real privacy concern is all the information you have to share about yourself and that can’t be avoided, regardless of the platform, you have to give details about you because that’s the entire reason you would be on such a platform to begin with, to make yourself known.
What you can do is leave out all the details you’re not comfortable sharing publicly and instead wait for recruiters to eventually ask you for those themselves, so you know that it only goes with one party that you have interacted with and can “trust”, rather than the wider internet.

As for the email spam, there are a LOT of bs emails you receive by default from LinkedIn, but you can disable them, it took a while for me to figure out which is which because they have so many settings, but now I managed to have only what I care about, which is pretty much requests for connection and messages.
Also you don’t have to install their mobile app even if they bug you about it, you can get by with the mobile PWA and if you want to do any Easy Apply job applications, you can just temporarily switch to desktop mode

Im no linkedin and don’t get bombarded with thousands of emails and targeted ads. My email is on my resume that I send out as well. I don’t see how I can be in the job market and not disseminate my email. You could limit your self to jobs listed on companies websites but you will still need to make a thing with workday or whatnot very few do their own system.
