Morgan Stanley Sales & Trading Analyst interview questions

For the first interview, MD firstly asks me to go through my resume, and then some typical questions such as why Sales & Trading? What's your greatest accomplishments? No technical part is asked for the first interview. For the second interview, my interviewer is an analyst. She gives me 5 mins to go through my resume and asks me to pitch her two stocks. Finally, she asks if there is any question I want to ask about her. I can't come up with an answer and feel I have screw up my interview.
