The interviewer is not actually interested in challenges you faced. He is interested in how to handled them. So simply prepare a good story about how you overcame adversity and solved a huge problem with an extremely intelligent solution. Interviewers love that kind of stuff.

* Solid advice from csmdev-- Managers want to know how you think. Might add in describing your results, include how your solution impacted the bottom line by helping to save the company money or increase revenue. It shows you understand the big picture and care about the larger business needs.
