If by “Standards” you mean the requirements to transition to United in the Aviate program, here they are:
-Meet the hours and years required flying for a United Express carrier and continue flying for that carrier until receiving a class date.
-Have a college degree (strongly preferred - basically required).
-Meet United’s requirement for acceptability in reference to Training Records, Attendance Records, and Discipline Records

Have a successful interview just like every other candidate that interviews at United. It is the SAME interview, the same minimum qualifications, the same everything.
