Accounting Clerk Question:

This question creates a great opportunity for you to reiterate your value proposition. If this company didn't already see reasons to hire you, you wouldn't have received an interview. Re-establish those reasons by being prepared to expand on information they already have in your resume and bring focus to those times where your involvement proved beneficial. Additionally, you may point out an area of "pain" you happen to know this company is experiencing and then offer your ideas for a solution.
