I was called for an interview in February '05 and, unfortunately, also did not get it.
Like Waldon, I went to HPA for the type, but I am 100% civilian. No military time. From what I have heard SWA likes to hire 50% of each.
Also, Like Waldon, I too think it was due to the slowdown at SWA. I was offered the interview in Jan, when they had 32 of USAir's B-737's coming. But when I arrived at the interview in Feb, they had lost the contract. Hence only 3 out of 12 got hired. I am continually updating my info on the web in high hopes of a Feb '06 re-try.
For what it is worth, here were my stats at the time of the interview.
-Bachelor in Mechanical Engineering - 8 years design work at major airline.
-4900 total, 1700 PIC in CL-65.
-37 year old, white male, married with 1st child on the way.
Good Luck and whatever you do, DEFINATELY do the interview prep course!
Hope to see you (and Waldon) in class early next year.
