This was for a university placement student position! I applied with my CV and cover letter, then received an invitation to an "informal chat" which was handled by the current placement students I would be replacing. They basically asked interview questions in an "undercover" more casual way about what I think the job role entails, my experience and my strengths and favourite Unilever brand. After this, I was invited to an in-person assessment center which I was unable to attend due to travel limitations and Unilever responded with flexibility and made arrangements for me to do an online assessment center with the student I would be replacing and the person who would be my line manager. This consisted of simple excel tasks, and an innovation task in which a case-study was shared with me prior to the assessment day where I presented my ideas on an improvement I would make on any of of their products and include supply chain operations and financial details. And finally some quick math questions. After this I was offered the job as soon as the assessment center was over.
