IMC Trading Summer Internship Program interview questions

The application consists of several steps, after your resume and motivation letter has been considered. First, there is an online skill assesment in the form of several mini-games. Those are used to map your strength and weaknesses (I think it was kinda of accurate), and verify if you indeed fit for the job. Afterwards you are face with a brief online interview (registered), you have to solve really basic problems in a short period of time and answer some questions about your interests/expectations and so on. The real challenging part come next. In the third part of the interview process you are faced with an online Q&A. The problem range from "finance" knowledge, expecially how a "Market maker" operates in detail, to logic/mathematical problems. They expect to see speed in execution, a fair amount of precision (you don't have to be perfect) and a prompt reaction to errors made. I know the interview process would continue with at least two other board of examiners
