Brush up on FX and hedging strategies using Derivatives

Hi all,

I used to work on the FX, Rates and Commodities desk at one of the big banks and got laid off back in March. I want to brush up my knowledge on some of the things I learned back then from strategies using derivatives such as plan vanilla options or digital options. Can you please recommend the best way or the best books you're aware of. I have a few interviews lined up so want to be ready to rock n' roll.

Thanks very much apes
