Hey Gullwing,
What are you, nuts? Take the job offer! What on earth would make you not take it? Awaiting a call from United? Perhaps you think that after 11 YEARS of trying to get on there, that they will finally take pity on you and invite you in for an interview. Even if they did, you might not make it past their process. Frankly, it doesn't appear that they're interested in you. Don't feel sorry for yourself. It's not you! It's the system. Take the offer! Do well at your new airline. Put United out of your mind... then, if they call, you can come back here and ask people you don't know, what they think you should do. I mean really, unless you're independently wealthy, and don't need to work to eat, you might just chill out until you get that call from United. Common sense would tell you that a bird in the hand is worth more than two in the bush. Best of luck with whatever you choose, but choose wisely.
