Citi Programme Analyst interview questions

Round-robin of inteviews. Three people total for their 'superday'. Each person is assigned a different category to interview. They included: personality, background, and technical. The technical interview consisted of writing out code for several different algorithms. I was asked to write out a function that traverses through a linked list in reverse minimizing the amount of times through. Also I was asked about different sorting algorithms and to write them out. The two non-technical people were easy to talk to. The technical guy had no personality, so sense of humor and seemed like he'd rather be at his desk doing work than meeting potential employees.
