MSCI Associate Financial Engineer interview questions

Very, very, very slow. It took me 3 months. Never spent so much time on one interview. Applied for Financial Engineer position. After 1 month, received call from HR. They sent first HackerRank test set. Nailed it. After 3 weeks, 2nd round was set up. They suggested for other positions, Quant analyst and structured products researcher. After interview, they sent home assignment. Writing a python script for pricing american option on a stock. After, they suggested original financial engineer interview. Again 2 rounds. 1st round was technical. 2nd round was more soft questions. Do you like work in teams or alone? What did u study at the university? Home or office? etc.
