Your answer to this question should showcase your problem-solving skills and how you react to unexpected challenges. The interviewer may ask for a situation related to your previous experience working with data, as specified in the question listed, or may leave it as more of a general question about dealing with challenges. If you have not experienced the specific situation, think of how you would approach the challenge if you encountered it in the future.

"While working in my previous positions, my teams and I have always strived to anticipate data issues that may occur during the ETL process. However, inevitably, an unforeseen issue or circumstance will arise. In particular, I worked for a company that included a franchise system that required data to be collected from a variety of locations and systems. One of the franchisees changed his system without notice which created loading issues for his store's data. I worked to develop a short-term solution to get the crucial data into our system for corporate-wide reporting and also began developing a long-term solution to avoid similar situations in the future.
