Scam call fishing for personal information. After talking over me several times insisting I had filled out an online survey, I got frustrated and screamed some obscenities at the guy. He hung up.
Got a call asking if I filled out a job survey. Start asking for citizen status, if I took out a student loan. When I interrupted the questioning to ask more clarification of who was calling they hung up. It appears they are collecting personal information to complete profiles be aware.
