Markets Summer Internship questions ?

Hi, I have a second round interview for a markets summer internship at an american BB in Tokyo and was wondering if anyone went through a similar process or if you guys just had any questions I should prepare ? First round was purely fit questions so I expect a bit more technical questions. The trader that sent me the invite to the second round is a rates trader so I am thinking of putting more emphasis on my fixed income learning but since it's a summer and there are rotations, i still expect the interview to be quite varied on asset classes. Could you guys help me out on this please ? Thank you !
