What you have done that show initiative and willingness to work?

I have always tried to do my best and I hope that my previous employers and co-workers can back my words. Personally, I like challenges and I am always trying to find new ways of doing things. That does not mean that I am perfect, but I certainly strive to do things allright. Also, I do not mind doing overtime nor taking some work home if it is really interesting. That, besides being absolutely true in my case, should convince almost any employer ;-) Hope this helps and good luck to you every step of the way!
