BlackRock Analyst interview questions

I was interviewed by 4 interviewers, including 2 analysts, one associate, and one vice president. The whole interview process took about 2 hours, and each for 30 minutes. They all firstly let me do a self-introduction. Then, they asked several finance-related questions, such as durations, bonds, and interest rates. The position I applied is about the green package, and one of the interviewer told me that the candidate for this position had to be very hardworking and quick-learning.
