I got a call from an out of state number. The interview took about 30 minutes. It was very sketchy because they asked for the last four digits of my SSN. With my past experience in HR, I have never asked for sensitive information like that unless the individual was officially offered the position. When I kindly declined to proceed with the interview, they person I was speaking to said "that doesn't matter...we have a lot of people interested in this position anyways." They were incredibly unprofessional.
