I've heard El Al is especially paranoid, but I had a pretty horrible experience flying out of Tel Aviv with Wizz Air in 2017-02 where Israeli security asked me tens of questions on several different points during my navigation through the airport, and then finally my MacBook Pro failed the security check and was confiscated—I was told "you are not allowed to fly with this laptop." They sent it 48 hours later on the next Wizz Air flight. Huge pain in the ass. sigh
