Required to take a test from Previsor (a Brainbench test), first choose C++ and the test consisted of probably 50% STL questions, which I was not comfortable with, so after doing awful on the C++ test I took the C test, which was much easier, mostly questions dealing with pointers, remember one on using bitwise operators to swap variables without a temp. I reccommend taking the C test unless you are very comfortable with STL/MI/namespaces/etc. All in all, I was rejected and spoke with a kid I know who got the internship last summer, the online test was not required for him so might not be necessary...

The first interview was at my school with two representatives in Technology at Bloomberg. They were easy-going and asked only technical questions related to programming, algorithms, and data structures. The final question was code related and relatively easy. Response is fast at Bloomberg, and I received 2nd round interview approval 2 days later. There were 3 interviews: 1 HR, 2 technical. It was quite tough but luckily they don't expect you to get everything correct. Everyone was friendly but demanding. After the interview, I received an offer the very next business day. They work fast.
