I struggle to see why they would this week interview anyone for a 737 (or indeed any other fleet) job when they have just advised that all contract pilots to finish end of Oct (
AFAIK +/- 15 737 Capt 7 F50 Capt) & have tomorrow the second planned meeting to discuss with local pilots whether they want 75%time with reduced salary, OR just reduced salary

I believe they have furloughed the last trained Q400 guys (unpaid I guess) for 4mths , and seem generally to be propogating gloom & doom for the Winter season.
Perhaps you should ask some pertinent questions at the selection & let us know what the "official" plan is, because we sure can't figure it out.
