There is no secret handshake or networking required to get hired by a regional these days. I would not go to the job fair because it could show that you are not intune with the requirements of the company you are seeking employment with. If the requirement is 800tt and 100 multi, than that is what it is. Unless you go to a college who has a bridge program with Eagle and lower tt time is accepted. Don't waste your or the recruiters time if you don't meet the requirement.
