Bloomberg Intern interview questions

I applied through my campus career fair. They called me for an on campus interview. The first interview went well so they called me in for an interview the next day. After a month, I was invited to do an on-site interview. They asked me a question about linked-list reversal which I answered correctly. Then HR sent me a rejection email the same week.

I applied through career fair and heard back from them after 2 weeks. 2:1 interview about C++.
