There are two rounds for technical problems. One is to solve the algorithm problems, another is to answer some quick questions about the operating system. The question is not so hard if you prepared well. However, I didn't do the leetcode problem at that time. Then, there is another recruiter asks you to introduce yourself as well as your projects. You can ask your questions to this person. The recruiter seems all very nice, but I still didn't get the offer unfortunately.

I was reached out by a recruiter to interview for a contractor position on a trading team. The question they asked was strange and nothing to do with the position.
