From my previous post on this thread:
For those interested:
4800 TT (all mil turboprop)
4670 ME
2550 ME PIC
Submitted app 3/1/08
Interview E-Mail 3/13
Thet said to expect to see required paperwork E-Mail week of 7 April

The invitation is for SFO first week in May. I have seen other posts with folks offered interview in NY around the same time. Not sure what you mean by "start date."

On a side note, if you have been invited for an interview already, is there any advantage to attending there job fair April 12? Are they conducting spot interviews at the fair?
