Two rounds. The first round was the "classic" interview with the HR and Manager. That was quite easy since they did not have any sophisticated questions, only regular ones... "what is my background, my willingless to work, my specialization, trading background and skills etc."
The second round was the Assessment center, which was held in Prague´s office. For me, it was quite an adventure, since it was the first AC in my life. Testing of IQ, soft skills, presentation, communication, and cooperation. Whole day. I passed and get the offer.
