I applied online. I interviewed at Morgan Stanley (New York, NY) in Mar 2012
Interview
I saw the intern information on my university career net and applied through Morgan Stanley website. Then they invited me to attend their written exam. It contain math, finance, and programming questions. About 60-70 questions, and you have one hour to finish it. The math part contains basic math and stochastic calculus. Finance part contains bonds, options and other derivatives. Programming part, you can choose to answer c++ or java.
Then I got an phone interview. One guy asked something about my resume. And asked me soem technical questions. And when it came as my first interview, I was too nervous to answer it well.
conditional probability questions: there is a test to test one's IQ. If your IQ is x, you will get a score between x-10 to x+10. Now someone's score is 150. What's his IQ range?
Can you tell the best estimate? If not, what else condition you need?
