Clearwire Development interview questions

This was the worst experience I have ever had. First, I was called by a recruiter and she conducted an interview by phone. After out interview she said she wanted me to speak with the hiring manager. 1 month later I received a call from that exact recruiter saying that someone would contact me for an interview for the position I interviewed for over a month before.......Well another month passed and I got a call about an interview. The phone interview went well, basic questions. To this day, I have not heard anything from a Clearwire representative. My attempts to communicate with them have failed. I guess I didn't get the job!!! To make matters worse, they recently reposted the jobs I applied for yet none of my calls or emails have been returned. Very unprofessional for an organization to not return calls. If the product is anything like the interview process, I don't want any part!!
