I applied through my university. There was a brief phone screening, then two back-to-back 30 minute interviews about a month later. The last part of the process was supposed to entail me creating a PowerPoint on why I should be hired and then presenting it in Chicago. I declined to do that last part. Two out of my three total interviewers seemed somewhat rude. Everything they said seemed to suggest (implicitly) that Kraft Heinz was a very competitive environment.

Amazing interview process. four rounds. They really try to get to know the real you. The last interview was a "super day" where they had candidates create a presentation, and have a panel ask questions. Gave you the opportunity to tour the office, taste test their products, learn from previous trainees.
