Questions i was asked during my GS Internal Audit first round phone interview.

Hi guys,
I recently created a post few days seeking advise on how to explain my GPA situation. Link below for reference. EDIT: I couldn't post the link but the forum topic is SCORED GS INTERNAL AUDIT INTERVIEW, PROBLEM WITH GPA

List of questions
- Tell me about yourself (walk me through your resume)?
- Why Economics (my major)?
- Why Goldman Sachs?
- Why Internal Audit?
- Talk about each of your extracurricular activities
- What made you start this finance/ investing club?
- Now the BIG question. I see no GPA on my resume why?
- I got this bonus question - What macroeconomic factor shows how an economy (i.e USA) is doing?

I hope this helps anybody. Now to praying and hoping that i move to the second round. Comment below for any questions.
