I would 100% recommend Haystack. When I've been talking to people who are looking for new roles, I've said to use Haystack.
Ray Blair
Lead Software Engineer, hired by EPAM Systems
Haystack definitely exceeded expectations and was much more streamlined than using a normal job board, or going through a recruiter.
