Phone call. The posting said experience in C++, which I did a long time ago, and I thought they would be more interested in checking whether I am a good researcher. He asked me "so do you do C++" to which I replied "I haven't in a while, but I could re learn it if I need to". He then decided to ask 5 C++ questions, one stats, and two math/brain teasers. It was one of the most awkward interviews I have had because at no point when I am thinking out loud he said anything. After I was done with one of the questions he sat there in silence of 30 seconds.

I applied through a recruiter. The process took 4 weeks. I interviewed at SUNRISE FUTURES in Sept 2023
Interview
The team leader kept talking about himself and asked no question at all (not even a single one from my resume or behavioral). Was informed I failed a couple days later and when I asked for feedback the recruiter simply ghosted me. Most ridiculous interview I ever got.
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
I applied online. I interviewed at SUNRISE FUTURES (Chicago, IL) in Dec 2020
Interview
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.
