Just had my hub interview in SF this morning.  来汇报一下。

1. Tell me about yourself, something not on your resume.
2. Tell me about your role at your current job.
3. Tell me more about the start-up you are doing (he was obviously interested in that aspect of my resume)
4. What are your goals, and why do you want an MBA. 
5. Why Marshall.   

-- all with in 30 min

That was all the questions.  I thought there would be more but... then I filled rest of the time slot(20min) by asking question, about the campus, activities, etc.

Overall, I think it went well, and USC will notify its 2nd round students after April 1st.  No message will be given before then.  No email either, you will have to log in online to check your status.

Also, they cannot make a decision until you submit official transcript.  These are few of the extra things I learn.   Hope this helps.
