Q:

What is your Greatest Success?

Answer

This is a good question to highlight your achievements. Don't be smug or arrogant about the success of a project, especially if it was a team effort. You need to give credit to the team, too. You could say what you contributed to the total project and also give credit to others that helped in your success. Don't be overly modest, either.Here are some pointers:


1. Pick something that was clearly a success and highlight your skills.


2. Pick something recent. If you pick something twenty years ago, they are going to wonder what you have done lately.


3. Pick something important. You may have succeeded in many projects that are not that significant. 


4. Pick something easy to explain. If complicated, give the short version.


5. Be sure to explain what you learned from this success.

Q:

How can the company’s compliance policies be improved and/or better applied, communicated and enforced?

Answer

Compliance policies should be accessible to all employees, well communicated, and easy to understand and apply. Responses to this question can provide valuable end-user feedback in this regard. The additional area of “enforcement” may provide some insight into an organization’s ethical tone and employee perceptions about fairness and equality. A quality compliance program will assure that all violators are treated fairly, but equally. If employees perceive that management or others are “above the law,” the compliance program loses credibility.
