I'm routinely shocked how biased people I work with are against individuals without a linkedin page. So many hiring managers across 15 years in my industry won't consider people without pages. One guy goes on rants how people are "sketchy" if they don't have a verified page and a lot of skill endorsements and testimonials! He'll pull up our vendors pages and check them out during meetings, complain if it isn't available or complete. I used to keep mine very minimal and locked down but I felt pressure from peers to flesh is out and keep it public which I hate.
I agree for in-person jobs.
For remote jobs with remote interviews, not having a LinkedIn page or having a LinkedIn page full of generic information that can be disproven by a quick background check are common traits of scam applicants.
A friend’s employer started requiring more verification after they hired a group of remote workers who would some times connect from North Korean IPs when they made a mistake with their VPN.
