To improve data quality and increase overall productivity of a system, Amazon AWS relies on their data analysts to use data cleansing methods to ensure quality data exists in their software. Be open and honest with the ways that you've helped ensure quality and accurate data in the systems that you've worked with while also showing that you have an open mind to learning and utilizing more methods if hired for this position.

"In my current work, I use a very methodical fashion in cleaning data for finished systems. My first step is to remove duplicate and irrelevant observations within the data. Then I scan the data to remove extra spaces, convert numbers stored as text into numbers and remove duplicate data. These steps help ensure clean and accurate data and I never overlook them. If hired for this position, what methods does the current data analyst team her at Amazon AWS utilize?"
