I applied through college or university. The process took 1 day. I interviewed at Citadel
Interview
Had 2 oncampus interviews, did not get a call back. Was asked about personal projects, then a couple coding questions like:
-Write a function that finds if a number is prime or not
-Code the in order traversal of a tree
-What is the game logic if you were to create a chess game in Java
Interview questions [1]
Question 1
What is the game logic if you were to create a chess game in Java
I interviewed at Citadel (Chicago, IL) in Feb 2013
Interview
Two 30 minute rounds on campus and three 1 hour sessions on-site if selected. It starts off with brain teasers and some general conversations. Can get pretty technical (C++ knowledge mostly) in the middle and they may discuss some things in the field of finance and will really appreciate if you show interest in Finance. Most important things going in should be to be comfortable coding in C++ and demonstrating an interest in finance which you should have if you want to work here

Question 1
Why do you want to work in this financial institution versus working in a pure software company like Microsoft, etc?
On Campus Interview, several probability questions, several C++ questions , several algorithm questions, in an hour. Lots of questions, need to move fast. You really need to know a lot about C++ and algorithm.
