Citi Quantitative Analyst interview questions

I interviewed with four different guys. The fist one asked me resume questions and some easy tech. The second one was horrible, I was asked by many market questions, such as what do you see the US economy in short-term, long term, how do you think of the equity market in the future, etc. The third guy asked me many math and probability questions, very easy, including the classic one (the prob that three random dots in a circle can form a acute triangle). The fourth one went through my programming skills and asked small questions based on different programming languages such as C++, SQL, etc
