Johnson Controls interview questions

I applied for 2 different positions Project Manager and Associate Project Manager. I was informed that I was not selected for the Associate and a second email that I have been selected for the Interview process for PM. The first phone interview was typical, then passed on to the second interview which was face to face. I had to travel to a different country for the interview. I requested a skype interview and was denied this opportunity. The face to face interview was meant to be with 3 Johnson employees including HR. The HR had to leave so the HR questions were taken over by the managers. The process took 3,1/2 months only to end up receiving not one but two rejection emails. I was very confused as during the face to face interview they mentioned the Associate Project Manager position, for which I had a rejection email from the beginning and invitations to Project Manager interviews.
