they’re cheap fucks.
This is also the issue with most tech job postings. I got this one job offer, entirely unsolicited from my end, to move across the country to Manitoba to a small town. They were going to offer up to $5000 moving costs. And the job was for a full stack developer. The salary? $42k Canadian.
I emailed them back telling them in blunt terms that their offer is insulting and far too low for any developer role.
