Honestly, I have no idea. This was my second time interviewing with them. I didn't get in back in the April hiring round, I know that I did struggle in that one, because it was my first interview in the aviation industry so I panicked and basically stuttered. However, I kept up with my materials from DX school, did refreshers and did much better this time around. Bill actually noted that he was impressed with my improvement and gave positive feedback so I was shocked when I didn't get the call. Still trying to figure out what they saw that I didn't notice myself.
