Another organization you might want to consider joining in addition to WIAI is the 99s
www.ninety-nines.org They also have scholarship opportunities. If you are a student pilot, you can join as a Future Woman Pilot member.
Best of luck to you. At the FBO I train at, there are no fewer than 3 females who are working towards a professional aviation career.
And as an aside, attitude plays big part in whether you interview successfully no matter what your field of work is.
