I applied online. The process took 3 weeks. I interviewed at FactSet (Norwalk, CT) in Jul 2010
Interview
Initially their response was prompt, which was encouraging. I set up a phone interview which went very well. I guess the interviewer was a little unclear about my C/C++ programming knowledge, so he asked me to write a 40 line program that reads data from a file and into a data structure, then allowing the user to query the list. Very simple. I turned in the program and it took them over a week to respond, only with that "Your qualifications were impressive; however, we feel that your background does not match our company's needs at this time." Very vague and unconvincing.
They specifically listed on their job requisition that ANY OO language, i.e. Java, was acceptable. I told them that I knew C++ well, just not as well, but apparently that wasn't acceptable for them. I understand that you may really want an experienced C++ developer, but don't state that other OO languages are fine and then completely dismiss me when you find out that C++ isn't my forte. Oh, and by the way, I've been programming for over 4 years and have my degree in computer science, so I do know what I'm doing.

I applied through college or university. The process took 3 weeks. I interviewed at FactSet (Hyderābād) in Dec 2025
Interview
It was a very casual interview. I was told the interview would start at 8:45 AM but it started around 10 AM. The interviewer was very friendly and walked me through my thought process towards solving the given problem. There were two rounds of interviews, purely technical though I did not get shortlisted for the second round.
