How UAL racks and stacks candidates is unknowable for sure. But a few datapoints to consider are that Chief Pilots are not doing a lot of Meet and Greets, Chief Pilots ask if you have done any of these job fairs, and most, but not all, getting interviews did.

Other than that you can scrub your resume and application, collect recs from friends at UAL, update your application flight time, medical, jobs...whatever, monthly and prepare the way you are comfortable doing for when you get the call.
