a) they have at least replied
B) it doesnt matter anyway.
I have friends who have been called for interview by phone and the day that they are leaving through the door for said interview a PFO has landed on the door step from the same company.
Letters back from the company mean nothing. Its HR's method of doing there job they get the letter they responed with a general FO. Pass the CV down the line which may get filed in the bucket it may not. If your really lucky someones notice will have hit the desk 2 mins before your CV has and 2 mins later the cp will phone. If you don't answer its in the bin and someone else gets called
When you hear storys of CP's grabbing the top half of a pile and dumping it in the bucket saying they don't need unlucky pilots its true.
