We tried at Intern Avenue, hammered it for 5 years. IA was a startup which created a self-service platform to find an ideal early-stage talents (interns and graduates) for businesses, using machine-learning. We had a good success and high retention rate at smaller size businesses, especially in non-STEM sectors, such as marketeers or journalists. We made many mistakes, but the biggest one was to assume that the recruitment decision makers in medium-size businesses are interested in the hiring process. That's not the case. We had to realise, for these internal recruiters hiring is a pain, an extra mile above their day-to-day responsibilities. Hence they hire recruiters. You can't apply ML on the behaviour and preference of the recruiter and expect an optimal output for someone else.
