I applied through university. The process took 1 week. I interviewed at DNB (New York, NY) in Nov 2017
Interview
The people are extremely nice. They called me in for only one round of interviews. Bear in mind I had met them on campus before however. There was two interviews and both were led by one HR person and one person from the investment bank. They mostly asked behavioral questions and just wanted me to talk about my view on economics
Interview questions [1]
Question 1
How was your internship? What did you learn? What do you know about DNB?
It included a cognitive ability test along with a personality test. Aced the cognitive ability test and of course there are no right or wrong answers to the personality test. Got good summary though on it
