Linked in is hit and miss. I’ve applied for well over 1000 jobs in 3 years and gotten maybe three interviews off of it. One offer but it was completely different than the posting. And a lot are scams out of India parading as American companies.
I’ve had better luck finding the jobs listed, then going to the company’s website that the job is for and direct applying. Did that and landed my current job in just 2 days.
