Ok, here is the scoop. KAL is still hiring both Capt's and F/O's for the 737. I just confirmed this with Austin at Gap Aviation this morning. KAL cancelled the interview's for the 737 in May however, KAL did the same thing for the 747-400 in April, but there is a scheduled interview for the 747-400 in May.
So, send one of the contractors your resume' and good luck.
