Aethercomm Program Manager interview questions

Submitted cover letter & resume online. Received an email from recruiting department 3 weeks later to schedule an onsite interview with hiring manager. Went back and forth via email with recruiting department to find a window when the hiring manager was available. Arrived on time for interview and waited for the hiring manager. Hiring manager did not have a space reserved for the interview and spent a little time to get a space for the interview. The interviewer's manager joined us later and I provided a copy of my cover letter and resume for him to review. Discussed my background, company culture/structure, and job duties. I followed up via email 3 times with the hiring manager with no response.
