Resmed Software Engineer interview questions

I applied for numerous positions at Resmed, including software and system engineering positions. I was never contacted back by Resmed. Finally a recruitment agent contacted me for one of the positions in Resmed and I had a 1st interview with the manager and another engineer. They didn't even know that I applied for all the other positions. The interview went very well, feedback was very positive and apparently the manager was all brighteyed and bushy tailed about my interview. Next was a technical interview on site. I couldn't answer all the questions and the manager suggested that I be considered for a systems engineering position. I had another interview for that with 2 systems engineers. I thought the interview went well. They were quite suprised to hear that I oreviously applied for that position. Shows how well organised they are. I was promised feedback by the end of the week. Weeks went by with no feedback. When I finally did squeeze feedback from them, my 14years experience as a software engineer was not good enough for them. Resmed people have families to support. Your system broke me and my confidence.
