I did the assesment in June and passed it.
Expect the following: Personality test and IQ test. You can pratice for the IQ test by doing diffrent tests online. Personality test, just be honest.
Sim. Testing your CRM skills. We did raw data SID, VOR and NDB holding. No emergency. ILS on raw data and no FD. Aircraft is a fixed base FNPT sim configured as a ATR. Not allowed to use autopilot or FD. They are using diffrent airports so you can not know for sure were you will fly.
Interview. With a pilot and one from HR. Very friendly people. Talk about yourself. Why Icelandair. Give example of good crm. What is important skills for a pilot ++
Very relaxed and nice assesment. Good luck guys!
