SAP Concur Implementation Project Manager interview questions

I had one of the worst experiences interviewing with Concur. The HR person showed no respect for me and my effort I spent preparing for the interview and interest I showed for the role. She cancelled a few scheduled interviews blaming a hiring manager. It took more than a month to have the 1st phone interview, then never heard back from her. I sent a few emails asking for update, she did not pick up phone and once I noticed "not selected" note in my application profile asked politely for a reason I was rejected and brief feedback. I understand recruiters are not career councelors but I think every candidate deserves to be at least notified about the interview outcome. Very disappointing. I did not take it too personally because I read a lot of similar experiences here from other applicants and it is really a shame Concur employs such terrible HR personnel.
