How long does the John Lewis Partnership interview process take?

How should I prepare specifically for John Lewis Partnership?

Focus on three things: (1) the company DNA shown above — what they actually grade for, (2) the rounds in your loop, especially the round most candidates underestimate, and (3) drilling on the question types in this guide using a structured framework like CIRCLES or STAR.

Does this apply to engineering or design roles at John Lewis Partnership?
