I believe you, no judgement there. The thing is, and this may very well depend where you live, what industry you are in, and how lucky you are, but speaking strictly for me, LinkedIn has been entirely useless in finding jobs, in the sense that the jobs being advertised there were also on other job boards. I did not contact anyone through there ever (but did write email from contacts found on company pages), and all the recruiters who cold contacted had the most uninteresting shit to try and sell me. I was also told it was mandatory, but I could not have it and it would make no difference whatsoever.

All this to say, I hope you get as lucky. Good luck on your search!
