Boeing Business Management Rotation interview questions

I was emailed and called to set up an interview. setting up the interview seemed straight forward and the individual who scheduled the interview was friendly. I was told it was going to be a phone interview and the email I received confirmed that. They called me at the appropriate time, but were shocked that I was under the impression it was a phone interview. They must have scrambled to find a phone to call me on to conduct the interview on the phone. It was a panel of 6 interviewers.
