This is a tricky question when you aren't privy to the inner working of the company or the challenges the company's executives face. The best approach for preparing for this question is to do a bit of research online for any articles or interviews with their chief executive officers on this topic, such as the uphill battle facing the company's fierce competition with companies such as Instacart, Amazon and Target. Try not to be presumptuous or arrogant when delivering your answer. Instead, use it as an opportunity to showcase that you did your research on the company before the interview, and that you stay up to date with what is happening in the industry. This will display you as going above and beyond when preparing for your work, and being proactive in your training and knowledge.
