I applied through university. I interviewed at FactSet in Oct 2016
Interview
I had a phone interview which is basically a screening process. I have a background in data analysis but my interview mostly consisted of data structures and multi-threading. I couldn't answer clearly and it was definitely my fault that I didn't review data structures and threads to brush up the concepts. For any future aspirants I would advice you to go through data structures and threads.
