The interviewer wants to know if you are able to analyze a problem and come up with a workable solution. Show how you use your initiative to pro-actively make positive changes.
Describe the techniques you use to organize your work. How do you determine the importance and urgency of a task? What else do you consider when prioritizing your work - for example, the available resources to complete the task? Show how you are able to use your judgment and plan the most appropriate course of action.
Be specific about any daily, weekly, quarterly deadlines you regularly had to meet. Explain how you scheduled your activities to ensure that you did meet the deadlines.
Again have an example ready for the interviewer. Describe the situation, the actions you took to meet the demands and the outcome.
