UBS Sales & Trading Summer Analyst interview questions

Would you rather have a stack of coins as tall as the Empire State, or many stacks of coins on a 1 x 1 table going up to a ceiling 2 meters above it? (Not necessarily these numbers, but hopefully you get the idea) I mentioned I was taking Financial Economics in the first round so I was asked for the definition of put and call options. Also, during the phone interview -- "Do you follow the markets? What did you read about today?" Super day was mostly behavioral. Although I got the markets question again. Also, was asked to pitch a stock.
