They use a PCATD desktop sim for the eval....IF you get the sim.... only 4 of 6 the day I interviewed got the sim eval. ( both of the guys who did not get the sim eval did NOT get offered a position. )
It was configured like a Baron but was very straight forward. T/O... climb out then direct to a VOR for a hold... couple turns in holding... then direct to the OM for the full procedure turn ILS followed by a missed ....engine failure on the missed.... eval over.
They will more than likely ask you during your 2 on 1 interview that IF you were offered a job which crew base would be your choice. I was NEVER asked out right which certificate ....just base.
The tests are straightforward. Have your info for the PRIA paper work ready. Our whole group was done by 10 minutes till 1 in the afternoon. I was the last to go to the sim eval and the last to do the HR/Pilot interview. They called me while I was still at the airport with the offer.
Good luck.
