Waitrose Customer Service Assistant interview questions

Online Application, multiple choice questions. Telephone interview with HR. Group interview in branch followed by one to one interview with manager. All were relatively straightforward, just smile and be confident, that's what they're after.

One on one questions with manager. Based around skills such as teamwork, overcoming challenges, how you changed the way you've worked in the past etc. This was followed by being alone in a room with a set of 20 customer comments. I was asked to choose 3 of these comments and writing how to improve the situation, sustain it over time, and the long term benefits.
