BlackRock Solution Center Analyst - Summer interview questions

I had two rounds of interviews. The first round was in university career center. The interview was 1:1, and the manager was very nice. I think we had a pretty relaxed and nice conversation. Several weeks after the first round, I got an email to invite me to an on-site interview in New York. The solution team interviewed me one-by-one. Four officers interviewed me, and each interview lasted about 30 minutes. The interviewers are very friendly and nice. Their working environments look very comfortable and supporting.
