Bloomberg Financial Software Developer interview questions

I went to my school career fair, and I got an interview with Bloomberg by talking to them and solving their problems in place. There were 2 rounds; each round they asked me technical questions about hash tables, linked lists and also behavioral questions like "Have you ever imagined what you would do in our company?"

I was interviewed on campus ( University of Maryland ,college park ) . I got a call through career fair . The first interview happened at the fair itself, I was asked a simple mathematical questions , and a simple programming questions . Then there were 2 back to back tech interview .
