The interviewer is looking for evidence that you have some basic knowledge of the logistics industry. How you answer this question will indicate your experience in their industry. But this is also an opportunity to go further by detailing what you know about how DHL serves its clients in this regard.

Even if you have not worked in the logistics industry before, you should have conducted some industry-related research before your interview. Remember, the interviewer is not necessarily looking for a full understanding of systems and processes (depending on the level of role you are interviewing for) - they may merely be looking for an indication of genuine interest in what they do at DHL Logistics and how they go about serving their customers in this way.
