Take a job where you can get it. I hate to say it, but you could do far worse than GoJet. Plus, as a dispatcher you won't get too much beef about working there. The pilots are the ones taking 95% of the heat.
In this industry right now, you're lucky to have a job. Personally I would take it and run with it.
You're going to hear all kinds of negative things about Mesa, Freedom, Go!, GoJet, but in the end, they are all still jobs out there for unemployed qualified people. I'm not saying that I think they're good jobs by any means, but they are jobs none the less.
Good luck in your interview!
