SUNRISE FUTURES Quantitative Researcher interview questions

They asked interesting questions, including probability, statistics, math, brain teaser, algorithm and trading intuitions. Touching every aspect of what a quant researcher needs in daily life. They also introduced about their philosophy

The interviewer was very rude and impolite. It felt like the interviewer was against me the whole time. The interviewer first asked an easy coding question. I solved it quickly, and the interviewer said sarcastically that 'Oh you obviously prepared for that.' Then the interviewer asked several basic probability questions. As usual, I tried to think out loud when solving questions, which I believe is very standard. The interviewer then stopped me rudely and said 'you do not need to think out loud, just tell me the answer and that's all I care'. When I tried to ask him to clarify the question, he said 'come on, you're a statistician'. The interviewer is the rudest I've ever encountered. I got rejected two weeks later but I did not want to work for them either. Luckily I've already received offer from companies that are higher at my list.
