MSCI Summer Internship interview questions

Received an invite for a 'call' half an hour after applying. It was a competency-based introductory call with someone from recruitment, who went through the company format and internship opportunities being offered. I was told to expect to hear back within 2 weeks, and when I did not, I sent a follow-up email. It took 2 emails and 4 weeks for me to get a response - was told that they had interviewed someone else for the role, and was not provided with any feedback.
