Describe to me a data project you worked on in the past that you would do differently with the knowledge/experience you have acquired up to this point and/or new technology that was not available at the original time of the project.

This is a Behavioral question, which the interviewer will use to determine how you dealt with a specific issue in the past and how you would deal with it if you encountered it again while working for their organization. Behavioral questions are best answered by using the STAR format. STAR stands for Situation, Task, Action, and Results. Using this format will help you organize your answer and lead the interviewer through your story in a systematic manner.

"In my current position, we performed analysis on a large set of data to determine why the company didn't achieve the results they expected from a major initiative they had implemented (Situation). Management had a hypothesis and expected the analysis to confirm it (Task). We completed the analysis, but the data led us to reach a different conclusion (Action). My colleagues and I repeated the analysis but used a modified data set and different analytical tools, and this time, the results matched the original assumptions. However, when management implemented changes based on this study, the results were the same as before (Results). I learned to be true to the methodology and let the results speak for themselves so the problem can be accurately identified and addressed."
