Citi Quantitative Analyst interview questions

-went through resume -background check for computational method and programming language

The intervew process was a part of On Campus Recruiting process. While the interviewer was polite and methodical in his approach, his Math questions were made by him in an impromptu fashion and asked immediately. This was particularly frustrating and unnerving. Since all his questions were not perfect and had some information that was not provided, I was not sure what type of answer he was expecting. All in all, it seemed like one of those interviews in which if you approach to problems coincided with that of the interviewer, your through otherwise you are not regardless of your scholarly potential
