Honestly unless I'm planning on quitting my current job, or if I were unemployed, I just ignore the linkedin.
Sure they spam you with "XX wants to connect", or "I'm awaiting your reply" emails. But real contacts and friends can call/email you, and everybody else can wait six months.
Despite only connecting with actual people I've worked with, not recruiters, I still get "suggested" posts which are slop, and "that happened". The site is a cesspool.
I haven't had LinkedIn since... 2014 I think.
I deleted my account after I got my first job offer and have never used it since.
If people dislike the site so much, I don't understand why they don't delete their account. Is there any value provided, or is it the fear of missing out on potential future value?
Every single job app I filled out in the last two years asked for my linkedin url. I don't know if not having one was disqualifying, but it does worry me.
