Quite easy, no need to prepare much before the interview. However I can recommend, and it would be wise to review some basic wording regarding capital markets. Fist call will be with India, so prepare for lack of understandig, but lets hope you are going to understand everything clearly!
It was a very easy interview. At least in my region. I felt like the pass rate was high. I was also assigned to different team that I previously, so keep that in mind..
