I applied through university. The process took 2 days. I interviewed at FactSet (Austin, TX) in Feb 2019
Interview
It started out with personal questions for about 10 minutes. Then, I was asked brief questions over time complexity, basic data structures, and sorting algorithms. After that, I moved on to the whiteboard and was asked to implement a binary search tree object in Java. Finally, I asked to write out a simple tree algorithm on the whiteboard.
Interview questions [1]
