I am contacted by recruiters at Zycron at least once a month for Roles in Project Management, Product Management, Product Owner, etc. They never review my skills, I end up in a fairly lengthy process of preliminary interviews, and then they ghost. Without fail someone else at Zycron who also hasn't reviewed my skills contacts me for the same or similar role a month later. These people are clearly mindless drones. If linkedin had a block feature for a company, Zyron would be on that list.
