Understanding the total scale and scope of what you do is important to the interviewer as is your ability to plan and execute an activity with a defined result in mind. So when you're asked about what types of vehicles you're experienced with, the interviewer is also looking for why and when you used them, for what purposes and what ultimate results. Always try to give concrete examples of the various successes you've had while performing activities related to the job. If you've gone beyond expectations or outperformed or outpaced others in similar roles, that can also be highlighted in your answer.
