Made it through the Alaska interview process. I was reluctant to invest in some professional interview prep. After enough friends that just recently made it on at other majors suggested I not have any regrets I made a quick google search for a company. Centerline Interview Consulting came up... (

I currently live in Chicago and after a couple quick calls I was set up with an in-person prep session on short notice that worked with my flying schedule. The backgrounds of the 2 guys, Keith Steele & Blake Ridgeway, I worked with are diverse and beyond qualified to help you feel confident. They have great access of up to date gouge and really helped me add structure to what I wanted to convey in an interview. They were sure to follow up with me even after the in-person prep with phone calls and emails that supplemented any worries I had about any aspect of the interview. Really glad I had them in my corner as I set out to get my dream job with my number one choice. It definitely helped take some of the pressure off. I hope you'll at least take a look at what they are offering when that call comes your way from any Airline you're hoping for.
