I applied through university. The process took 4 weeks. I interviewed at Nasdaq (Philadelphia, PA) in Dec 2014
Interview
Good Interview, This was for the internship position in Philadelphia PA. They interviewed me on campus. Asked basic questions about my resume (stuff I worked on and previous experience) Asked me if I knew data structures such as Trees and Hash Maps, tables. Asked what the difference between an Interface and Abstract Class was. Could interface methods be defined, etc. Basic questions that you should have a concept of. It was my first "technical" interview when it came to coding questions (no coding was asked to be done though). Good experience and the guys interviewing me were awesome. Very nice and made the interview easy going.

Question 1
What's faster a Binary Tree or Hash map? - Wouldn't say it was most difficult but it was unexpected
