Morgan Stanley Quantitative Analyst interview questions

Submitted my resume online to their website. Then after about 3 weeks I got an email asking me to schedule a phone interview. We decided on an interview day and time. Then on the day of the interview half an hour before the interview time, I get an email from the HR person supposed to interview me telling me that a meeting a came up and they have to reschedule. We did for later in the afternoon. They later called. The person was just an HR person which reads a set of questions supplied and writes down the answers you give back. They have no clue as to the technicalities of the question. I was asked 5 questions, 3 probability questions, and 2 finance.

Math test. Then 2 interviews after 1 week. Then another 4 interviews after 1 week. Then another 4 interviews after 1 week. Questions on C++, Maths, Puzzles, financial products. Quants are very good and they ask generic math questions and c++. They are very reasonable and understand that one doesnt need to answer all questions correctly. They are willing to hire somebody with the raw talent. Interview process is long but enjoyable.
