BNP Paribas FX Option Trading Graduate interview questions

1: First Round: Numerical Testing 2: Second round: 1 to 1 interview with an FX trader. I think the questions you will be asked depends on the interviewer. My interview gave me an absolute hard time. I will say this was technically the hardest interview i have ever attend. He ask me questions for 1 good hour. No calculator allowed or materials what so ever. I'm not sure if i will be invited for the second round but i dont think i will. I managed to answer most of the questions correctly given the time limit. (Yes, you are not suppose to take too long to answer)
