IB SA in Sao Paulo

I'm a sophomore at a non-target in the US but ranked higher than the targets in Brazil (USP, since FGV and insper are not included in rankings). Im trying to get a Summer Analyst position and could only find some banks with those programs specifically listed (think BTG ). I used my family connections but could only get interviews in EB and other MM boutiques. Does anyone know how the bigger banks (BB's, Itau BBA, Bradesco BBI, UBS/BB, or firms like Seneca Evercore, Moelis, Lazard, IGC, G5, BR Partners) recruit in Sao Paulo?
