D1 recruiting coach reached out to son and a teammate their sophomore year, invited them to a camp. They went and got the "if we're interested we'll call you, don't call us" return email. Senior year, they invited the two back to a camp. I almost said no, I'm done with them, but son persisted. He and his teammate are both there now.
So yes, it's interest, but it may take a while to come to fruition.
