Insight Global Recruiter/Entry-Level interview questions

Was contacted over LinkedIn by an internal recruiter, Katie Nigrelli, and scheduled a phone interview which went very well. I then moved onto an on-site interview where I met with 2 account managers. After meeting with these 2 people and it going great I was told that the last couple people I was scheduled to speak with were busy due to a promotion in the company but that I would be contacted to schedule a lunch interview which would be the final interview in the hiring process. I called Katie,as instructed, to tell her how it went. She acted uncomfortable and brushed me off saying she would get feedback and call back. A few days later I received an email from her saying I would not be moving further. I had already received and accepted another job with another company but out of curiosity I asked why this would be the case when I was told I would be moving on to the next interview. She advised me that the account manager who told me that was not permitted to make that kind of decision but she would be happy to get me in front of a sales manager. Why would I want to do that after being rejected based on the fact that the sales manager didn't feel like talking to me that day? I now view the company as inconsiderate and this interview was a waste of my time. Even if I hadn't received another offer I would not have pursued this position based on the disorganization and disrespect of the employees

Got headhunted off of my linkedin profile, first round interview was fine. Had a family emergency right before the second round, tried to reschedule however the recruiter never returned my calls.
