Don't know quite how to put this, but I went to SIN for the "interview" process. Apparently, I was one of those who slipped through the process. I was successful in the simulator/medical and interview.
Was subsequently offered a class date. I did pass it up, not so much because of the paltry wages, but more for another position. I can tell you that given the company I am working for right now, SIA cargo working conditions are light years better.
I am rated on the -400 so there is no bond. For me, I was willing to see what happened, but fate played it's hand and another position surfaced.
