You should answer such a question honestly, and give an example of an experience you have had that paints you in a good light. Experiences when you have given good customer service will go a long way to show an employer that you can provide good service working for them as well, since you have a history of good customer service in general.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
