Hi
I agree with Gil. The thing with interviews is they want to see what action you took in the past in a particular situation since that is an indicator of what you would do with a sticky situation in the future. Also, from what I have read about this, an ethical dilemma is not a situation where a particular action you took was unquestionably the right path to take (eg. being offered a bribe but not taking it) - but a situation where you had an actual dilemma as to what choice to make (eg. having to choose to lay off in a downturn one person or the other when one of them is a superstar who has consistently gotten excellent results, and the other is an average performer but you know he is recovering from cancer and needs to keep the job for health insurance). I have taken some extreme examples, but you get the idea.
