Question 4 is almost illegal

It's highly unlikely that a trained interviewer of a reputable company would ask Question #4 because it's too easy for this to go wrong and runs afoul with the equal opportunity employment law.

Also, I would strongly recommend against anyone to try to compare him/her with American peers on GPA/projects/intelligence, etc. If the interview is an American, she would feel like "who the hell are you to say you are better than Americans?!" Be careful.
