Carrier Application Engineer interview questions

I got a callback within two days of applying, and had two interviews that same week. I was told during the second interview that I would be having an interview with the hiring manager. I was never contacted about this interview, and emails sent inquiring about my status for the position were not responded to. The listing was taken down within 3 business days after my interview, so I assumed they already had someone picked out by the time I was interviewed. Six weeks pass and now the job is listed again on the site, and my application still says "pending". I finally received an email telling me I was no longer a candidate 7 weeks after I submitted the application. The corporate recruiter initially told me he would get my application to the right person for other positions I was interested in, but did not return any calls or emails after the first contact. I can accept it if they don't want me for the position, but this dragged out too long, and I was lied to and ignored multiple times.
