Your answer to this question will offer insights into how well you've prepared for this interview. Accenture is a global professional services company with over 674,000 employees across more than 40 industries. Their offices and operations are in more than 200 cities within 50 countries, serving clients in more than 120 countries, with 185 partners in North America, Europe, and other growth markets.
With offices spread across the globe, they're likely evaluating whether you are a good fit for this opportunity. They also want to know how flexible and committed you are. Thoroughly explore the details of the job posting and their website, and look for any indications whether travel is a requirement for the position. If thorough research yields no answer to this question, then asking clarifying questions is perfectly acceptable. Just avoid asking any questions you could easily have answered yourself.
If relocating or traveling for work does not interest you, refrain from saying so. Ask clarifying questions, expressing that you'd like to know more about what that looks like in context with the expectations of the role and that you are flexible and open to further discussion. This way, you keep your options open rather than shutting down any interview negotiations.
