Citi Management Associate interview questions

I was asked basic questions concerning my knowledge of current economic trends, and what my solutions would be to the problems being faced. Was asked to give a personal definition leadership give an example of a time when I had to lead a group and what challenges I faced. Also my CV stated that I once worked as a finance volunteer, thus I was asked a few questions pertaining to ratio analysis,of which I failed to properly articulate as I haven't come across ratios in quite a long time.
