What kind of experience do you have traveling to client sites?

This question often serves as a method to narrow large pools of candidates. Most companies believe it is important to determine a candidate's comfort level with travel scenarios upfront and may include this question in a phone screen interview.

Interviewers expect answers such as 'occasional,' or 'up to X percent of the time.' Many IT business consultant assignments require travel to various client sites and will include the job requirement details within the job description of a specific role.
