I thought they wanted the 121 experience as well! I am not trying to be mean to guys with low time of no 121, but I was told they were looking for this! Anyway, I am not sure why they are interviewing guys with 500 when guys with the previous 121 have 2500+ hours and don't get an interview! I have seen this in the past, but usually with small charter outfits, because they don't want people who won't stay there long because they already have a lot of time. They would rather have lower time guys that will be around longer. Just one example.
