Autotrader Inside Advertising Consultant interview questions

I was e mailed by one of their on line recruiting specialists about this opportunity so I went in an applied on line for the position. I was set up with a telephone interview and at the end of the interview they e-mailed me an on line assessment at which time I was told they would get back in touch with me . I took the on line assessment and have not heard anything back since then and it has been over two weeks . I e-mailed the interviewer and have not heard anything back in over a week . I find this very unprofessional this company selected my resume and asked me to get in touch with them . Then they do not have the decency to get back in touch with me or even send me an e-mail about my status
