I would 100% recommend Haystack. When I've been talking to people who are looking for new roles, I've said to use Haystack.
Haystack definitely exceeded expectations and was much more streamlined than using a normal job board, or going through a recruiter.
I applied for the job and literally the next day Tom from Fuzzy reached out. It was 30 days from starting on Haystack.
