Help with a railroad question?

I just got hired in to Norfolk Southern a while back and during the hiring session, I brought along a neighbor with me to the hiring session. I made it through the first go around-she didn't. When she went, she only had her temporary license, but they still interviewed her and allowed her to take the assessment test as well and stay for the hiring session. They asked about it initially and she told them that she's going to take her driving test pretty soon and she would have her regular drivers license before they even start training. She's a really good driver-she lost her licesnse because too much time lapsed when it expired and she had to start all over again. Something happened and she was unable to take the test-I guess car trouble. In the meantime her temps expired and she had to hurry and get another one and it was the day before Norfolk Southern would be back in town. Thinking that she would be able to sit in for the interviews again, she shows up with it and tries explaining to them that she already has the exam rescheduled, but they immediately turn her away. Why would they let her in the first time with the temporary permit, interview her and all, but not this go around? I asked her was the same people there and she said all of the same people who interviewed us were there except for the conductor who was not there, but was replaced by some bleach blonde HR lady. She was the one that told her to leave. They wouldn't even allow her to stay.
