For the interview, 3 hours is allotted. My interview lasted around 90 mins from hello to goodbye. I'd say others were around the same or perhaps upwards of 2 hours. Never take any interview for granted of course, but in general it was very straight forward. Be prepared to answer a few TMAAT questions, why SkyWest, be able to give some good overviews on turbine engines, swept-wings, maybe some basic systems theory, and be pretty smart on your IFR knowledge. And most importantly of all, show that you're someone they could get along with for 4 days in the flight deck. If you can do all of the above, things will go well. Best wishes and do well!
