If you weren't aware travel was a prerequisite for the position and found nothing in this regard on their website or in the job description, ask if it is. Tell them you're still interested and that you'd be open to discussing it further. If your understanding of constant business travel doesn't fit into your current lifestyle, take some time to evaluate how this opportunity fits into your long-term career goals. Weight out the pros and cons if you are unsure while exhibiting consideration and flexibility. Ask more questions about the position, including if there is room for advancement from within, and if a willingness to travel is a prerequisite to growing in the company. Keep discussions open and exude flexibility with a focus on a willingness to go to batt for the team. This will exhibit big-picture thinking toward your career goals.

"International travel sounds fun, depending on its frequency. I am flexible, but I'd have to take some time to consider what that means. Occasional travel is one thing, depending on the duration. Relocation is another. I don't believe anyone would disagree that such a huge life decision should be taken with care. I'd have to weigh how such a decision would impact my personal life and my career goals. I worked for a company that had me traveling for work for two weeks on and two weeks off. Frequently, this took up my evenings and weekends as well, which was far more than they hinted at when I was recruited. Since this didn't shake out as advertised, maintaining a healthy work/life balance proved more difficult than I imagined. So answering your question, once I had all the needed information, I'd consider all options carefully."
