I am based in the UK and find it hard to find good developers/designers/product people. Although we advertise on our web site, unless people are looking quite specifically, they are unlikely to find the adverts (unlike FANGs which would attract candidates directly).
Also, Recruiters tend to be a poor and expensive solution. It is hard to tell the good from those who just claim to be good and we get a lot of noise from them. Also, I'm not sure that the best candidates just call a random recruiter to find them a job.
What are others doing to both find jobs and to recruit?
The local labour market for engineers, technicians and developers is pretty much empty - as in, everybody with the skills required and the desire to live here already does.
Recruiting more often than not means sniping, or, if we're lucky - that someone has recently found a partner with desirable skills and coaxed them into moving up here.
Anyway, we've found that word of mouth is the most effective way; we simply let friends and associates, former colleagues and whatnot know that we're looking for X.
This is a hundred times more effective than LinkedIn for vetting candidates - people are quite unlikely to uncritically recommend someone when they will be reminded of their sell-in for years if it is a dud. (Much unlike LinkedIn endorsements...)
It turns out with friends&associates, friends&associates' friends&associates &c, you can cast a quite wide net - and also, the sell-in works better both ways; the candidates who do show up for interviews already have been told ours is a good place to be and are, more often than not, a good cultural fit.
(And, before someone asks - 'cultural fit' means 'Happy to work in a rather unstructured madhouse where the unofficial motto is 'We've never done that before, so we're probably quite good at it!') - we've assembled a motley crew from just about every nook and cranny of the planet, from Sri Lanka via Belarus to Argentina and Japan and lots inbetween. Oh, and the occasional Norwegian. All making world-class subsea equipment on a small islet way out in the boonies.
