Remind me of that time when a recruiter calls me, says I'm not interested and I hang up, then my colleague's phone start to ring, same recruiter. We ask him how he got our phone number because our phones were provided by our company and the numbers were not publicized. "I received the list from a colleague, we have different way of sourcing our data, blah, blah, blah". Few days later, we learned that some guy from HR from our company left and sold the employees list to some recruiters.
