Are you open to travel with this position?

The topic of travel will almost certainly come up during your interview. Many large firms send their auditors out in the field for a good portion of the year. Even smaller boutique firms require several overnight trips a year. Given this, be prepared to articulate how much travel you are comfortable with (for example, 25%, 50%, etc). Most job descriptions will include the expected amount of travel. The interviewer is gauging whether you are a candidate that is willing and able to meet the travel requirement, so try to align your answer with the expectation of the role.
