Citi Quantitative Analyst interview questions

interview on campus and after one day I got the email to attend the super day in New York. The process is very smooth. The super day is very intensive. Very difficult.

The process took 6 month. There were 4 different interview whereof 3 included professional questions about my carrier and previous studies. They were focusing about my financial mathematical knowledge (e.g. stochastical calculus, differential equations) Everyone was really helpfull and kind. If I didn't know something they tried to help me.
