Hello, World are real professionals. I definitely recommend working with them!
Thanks to them, we hired a Senior Devops Engineer for a unique HFT project (high-frequency trading platform) in 1 month.
Recruitment funnel: 8 candidates were contacted, 6 successfully completed technical interviews, 4 finals, 1 offer, 1 hire.
We came up with a difficult test for the candidates, as we wanted to make sure only real experts join our team. The agency accompanied applicants at all stages of selection, always asked us for feedback, and adjusted the search strategy based on our comments.
