Received call to do phone interview from hiring manager, set up phone interview. We had (i thought) a productive phone interview and concluded that the next step was to come into RTP office for a face to face, closing remark was I would be contacted within 2 weeks to set up that face to face. I never received any notification and I made a follow up phone call and voicemail to the hiring manager at 3 weeks post interview. I followed up with an additional email and another phone call over the course of the following 2 weeks, did not receive any response. Total was 3 phone calls and 2 emails over the course of 6 weeks, no response to any of them. The reviews on glassdoor did not portray the company in a positive fashion, but my own personal discussions with existing and former employees was extremely positive. I think it would be a professional courtesy to at least respond declining to move forward, especially if the closing remark is to set up a time to come in to interview face to face.
