rr,
I understand your anger, however I see some positive things in this.
Nr 1 U got "invited" to EZ land, which is not so bad considering the nr of candidates out there. That means airlines ARE interested in U !!
Nr 2 U got a sim session "free of charge". Another good experience for the next recruitment schemes U'll attend.
Are U sure U failed due to your performance in the sim, or could it B something else ? In most sim sessions, "instructors" do not expect U to fly the a/c to perfection, especially when U've never flown it before. What they expect, however, is good airmanship, good scan & good CRM.
One last thing, most airlines look for a particular profile. U might B the best pilot around & still not get the job, because there's something else they want. On the other hand, I've seen people being hired despite a really poor performance in the sim (busting altitudes, landing @ Vref +50, etc).
Your skills may play an important part in the process, but personality & luck certainly have their role as well.
Good luck for the next one.
MF
