This is very true. Ever since I left the regionals for the majors, I have realized that 'acting the part' is so huge in GETTING an interview and how you act AT an interview.

Most (not all) major pilots take pride in their uniforms for many reasons, including pure professionalism, not wanting to be the sloppy one in the crew, they care how the public perceives them, etc.

I'm a strong believer that if you want to move up in this industry you've gotta be professional. Just my 2 cents.
