First interview is 30 minutes on the phone with an HR specialist. General questions, eg: Why Bloomberg? What does Analytics dept do? What Bloomberg products do you know? Tell me a recent story from financial news. What do you expect from the Insight week? A week later I was informed that I made it to the next level, which is a 30 minute online video interview with two team leaders and an online assessment with 11 maths/python/SQL questions. The interviewers were very friendly.
