SAP Concur Sales interview questions

Initial phone interview with recruiter was typical interview for sales job. Talk about your sales methodology, what's my selling style, etc. Recruiter said she'd let me know next or following day if I was moving forward. Two weeks later she finally writes back that I will go to next round and meet with 3 sales directors. A week later after some scheduling conflicts I go to the office a meet with the 1 sales director who isn't out of town that week. He's not the hiring manager, doesn't seem familiar with my resume at all. Interview was 20 minutes long. He asked me 3 questions. 1) why do I want to leave my current job, and 2) did it concern be I didn't have B2B sales experience. 3) What are your questions. Basically I spoke for about 3 of the 20 minutes and listened to him answer my questions. For real..It was so strange and uncomfortable. I had a more professional interview when i got my first job at 15. I got an email the next day saying thanks, but no thanks, moving on with candidates with B2B experience. OKAY, so why did I was hours of my time with a phone interview, prepping for 1:1 interview, etc.? I wasn't asked a single situational question, nor any personal/professional questions about myself, or my sales background, or how I sell. That was very suprising. Interviewer didn't take any notes (nor did he even bring a pen or paper).
