Group interview and discussion
We all spoke about a situational task and then presented our answers in front of everyone else
Overall good interview and then there was a individual interview after that
They asked 5 questions, Mostly talking about tell me about a time (STAR format) and how you would handle work situations. Make sure to know what sort of values Waitrose focus on and come up with examples that show those values in real life scenarios. I don't remember any motivational or technical questions.
Standard interview process, make sure you know what the partnership means. This is best to learn as a definition through their website which has a lot of general information on this.
