BlackRock Software Developer interview questions

1 short on-campus technical interview lasted about 30 minutes (interviewer came late). Called back for superday about a week later. Super day consisted of 4 back-to-back interviews 45 minutes each, 2 were technical and 2 were behavioral. However, I know different people got different combinations of technical/behavioral interviews too.

Tough super day. Some technical questions, some non-technical brain teasers. Four total interviewers that lasted about an hour each. There was no financial questions because they didn't expect any software knowledge coming in as an intern.
