The interviewer would like to know if you are targeting positions within the same industry and where Unilever ranks among the positions you are pursuing with other employers. Talk to the hiring manager about your desire for a role within their company above all. However, you don't want to look like you are putting all your eggs in one basket. If you have a deadline to find a new position, tell the interviewer. Talk about how many interviews you've had and how many more you anticipate participating in. This will inform them that you have a timeline and that there is competition, and could perhaps prompt them to make a decision more quickly.
