Well, the HR questions are more or less similar.
As for the technical questions, my group of friends which attended the stage 2 have different questions individually. They more or less ask questions base on your background for example there are some who are instructors so they ask them about instructing questions. As for me I just got my licence 6 months ago and i'm currently doing my 737 type rating so they ask me some questions about 737 systems and the rest about their 747-8F,747-400,A340-300,engines,holding (entries), TCAS, etc....
