Went through the whole loop in their Trading Tech team. Very typical hedge fund interview process except that they still give you Hackerrank consisting of 3 questions before they even talk to you. If you were to apply here, be careful, as they force C++14 instead of C++20 which nearly cost me being rejected right away as I had to rewrite C++20 into C++14... Down the line I had some zoom 1-1 sessions with various developers and HR covering many areas including live coding, design and behavioral questions. After that I was invited to on-site, which was fairly unpleasant experience with some people trying to put you down by asking you tricky design question few minutes before time runs out (I did answer this one and the interview looked *sad* to see I could pull it off) or start *assuming* that if you were to join, you'd make a lot of bugs / mess there...I had an urge to leave ASAP during the interview and felt something was odd there. One week later I got totally made up feedback which was completely off the target. I understand someone did not like me personally and that is totally fine, but they could have just ghosted or provided a typical reject line, but instead they choose to provide a fake one. Generally looks fairly mediocre, particularly they struggle to strike the balance between vendor and custom solutions, and it appears they like to reject many candidates in order to keep their internal value high.
