A very easy phone screen followed by an onsite interview in NYC. There were about 15 interviewees on the super day. We began with a tour in the Bloomberg Tower (learn about their terminal, TV station, etc.), and then the 2 on 1 interview. There are two rounds of technical interview. The questions are all quite unusual, basically one of my interviewers did not prepare any questions, simply thinking of things to ask me when I'm talking. All very interesting questions, but a bit challenging -- not tricky, but kind of vague and hard to explain. I already knew at the time that I didn't do well. The people I met during the entire process were all super nice and friendly. The experience was good overall.
