Flow Traders Graduate Trader interview questions

4 different steps, the first one an online Math Test, consisting on 75 mental calculations. The second one an interview with the responsible HR and the third step consists in an interview with both the responsible HR and a trader of the company. I didn't pass the third one, I know there is a fourth one but I don't know what it is about. I think you are asked to solve a business case. The second interview consists in questions regarding describing yourself and your education, your motivation for becoming a trader and few technical questions concerning the core business of the company. The third interview is more technical. After few minutes describing yourself and your motivation, the trader will start asking you more technical questions regarding the core business of the company. Finally you are asked to solve 2 brain teasers in a given short time ( I remember 2 minutes for each brain teaser). I suggest to strongly prepare for all the interviews and the Math Test. The firm will give you very useful indications on how preapring each step in the best possible way.
