I just flew with a captain who is one of the many interviewers. The way he described the process to me seems that it is somewhat on "autopilot" until the prospective candidate gets to the simulator and the interview. In other words I think you get points awarded electronically to get the call. I imagine it is possible to put negative points on active Guard pilots, but given the number of current Guard pilots on the line and at the training center this would be hard to keep a secret and I would consider that rumor highly unlikely.

On a separate note I would add that the captain who does interviewing said that at present we are accepting about 80% of the pilots that make to the interview process, but many interviewees are showing up in old loafers or similar non-interview like attire. So my one piece of advice to any UAL interviewees is to dress sharp; it helps make a favorable impression.
