Wow, running interviews on a Saturday?! They sure are desperate.

Just remember ExpressJet need you more than you need them. They may be interviewing you, but you're also interviewing ExpressJet. I'd come to the table and ask the tough questions. (possible future flying, Company Shrinkage, Skywest relationship, attrition numbers, stability of contracts with mainline partners, signing bonus, etc)

Of course, recruiters aren't paid to tell the truth. They're paid to get butts in the seats. So, no guarantee anything he/she says will be truthful.

Be cautious and good luck!
