Just to give you guys an update....
It appears that Amtrak has chosen not to hire me for the position. After my interview last Monday (which I thought went extremely well), I was told that I would hear something either way by the end of the week, since the training program begins on 10/4. Well, I didn't hear anything all last week, so yesterday morning I called the HR rep in Chicago who was one of the people who interviewed me. He was not there so I left a brief message basically asking if I needed to do anything else, and also thanking him for the chance to interview with Amtrak. Thus far I have yet to hear back from him, so at this point I can sort of read the writing on the wall so to speak. I guess there is still a faint chance that I could get the call, but with each passing day, the odds get smaller and smaller.
Such is life. All I can do is hold my head up high and be proud of the fact that I really made a strong effort to better my career.
