I applied through university. The process took 1 day. I interviewed at Optym in Mar 2011
Interview
Interview process was tough. Questions were majorly asked on data structures and algorithms. A high GPA helps for a position in this company. Some database management questions were also asked. Some programming problems were given, you might practice some from any programming contest website. It might help to review optimization algorithms like shortest path, linear programming.

I applied through university. The process took 2 days. I interviewed at Optym in Sept 2014
Interview
Applied at career fair then interviewed in campus. Technical interview, with questions related to logic, programming, data structures, operations research. The answer expected on most questions is not necessarily the most obvious, they are looking for the most efficient (least number of steps). It is key to be familiar with the concept of complexity of an algorithm.
