In that case, take the cargo job AND take the Hogan.

There are no assurances that you will "pass" the Hogan nor the interview. You can always say 'no thanks' to UAL later if you decide the remain local, but if you want to come to UA you'll want the earliest class date in this hiring environment.

Considering the current interview dates (and associated class dates) this will give you a few months to ponder your options.
