If asked this question during your interview, the interviewers want to know where this job scales on your wishlist and if you are under a timeline to secure a position. They're also likely looking for assurances that you want to work for them and aren't playing the numbers game and looking for any job anywhere.

Let them know that a role with Kraft Heinz is at the top of your wishlist, but be honest if you're actively looking elsewhere and express that you are being responsible in your search. One way to do this is to keep an organized folder with every customized resume and cover letter you've submitted to each position you are interviewing for, separated by tabs, with notes on each interview and a breakdown of the pro and cons. Most effective interviewers have something similar for the applicants they're interviewing.

Just have it with you, with a tab containing the materials you've prepared for this interview, trying to keep the other tabs for your eyes only. That will indicate that you are an organized professional taking all your prospects seriously. It will also present you as a desirable candidate.
