Viewpoint Inside Sales Representative interview questions

Very Unprofessional )The interview process was rather basic. After they contacted me several times offering a F2F interview I took time away from my currant position to meet with the sales manager. After completing the inter view I sent a professional follow up letter. While considering this opportunity I sent another email asking if I was still a candidate for this position. I also followed up with phone calls and other emails ( this all took place over a 3 week period, so I was not being aggressive) They have not had the decency to reply to any of my contacts. I was only trying to review my options before accepting another offer. Very Unprofessional !!!During the interview I felt as though I was consulting rather than interviewing. The sales manager did not seem to come from a sales background.
