This was for a college hire position starting in June. About a week after filling out the application, I received an email requesting a pre-recorded video interview. It consisted of five questions with an allotted minute for each of your answers. Do not go over time because you will get cut off. The questions tested your knowledge of Bloomberg and your overall personality so it was not too difficult after some basic research.
About a week after I submitted my responses, I heard back to attend a super day at their Princeton office, which is where their Global Data department is located. It was an all day affair and consisted of three different parts: a group debate, a skills assessment (stats, python, SQL, etc.) and a workflow improvement roleplaying exercise (by far the hardest part).
After completing the super day, I found out pretty quickly that I was selected to have a video conference interview with one of the managers. This was more akin to your basic personality based interview where they ask more about you and what you know about the role. For me, since I was a college hire, they asked about previous internship experience and extra-curricular activities.
After this interview, I was invited back on campus to have two separate 30 minute interviews, 2:1, to gauge for which department I would be a best fit. Again, these were personality based so not too bad. Overall, the interview process was very rewarding and HR was super helpful throughout the whole thing. A couple weeks after my last set of interviews, I was made an offer.
