Yes...HR type interview...if there is low turn out expect the 50question ATP test and mech. apt test too. Good oportunity to meet Camille and get a foot in the door.
No...SLC is somewhat Jr. ORD is the jr base. Most people get their domicile of choice out of class, except maybe SBA, DEN, SAC. Lots of movement in ORD.
Lines are okay in ORD. Lots of standups and 4 day trips.
Hiring is supposed to go on for a while...(9 mo..maybe 12 mo..) Current upgrades in EMB about 14 mo and in RJ about 28 months.
Good luck.
