If you flew a different airline to get into Israel you might well escape the interrogation but flying out is a different story. Everyone, no matter what airline he is taking, is questioned.

You don't "do" interrogations? No problem. Just be prepared for a long bus trip to Cairo or Amman. It requires no interviews at all and you can buy a ticket on EgyptAir or Royal Jordanian to take you home.

(Of course, I can't guarantee that you won't be questioned in those countries. Their own security forces might be curious about why you were not allowed on a plane out of Israel.)
