his post is q old now but hopefully future applicants will see this and it will help.
I had my assessment centre yesterday and I thought I’d outline the day whilst it’s still fresh in my mind.
There are usually groups of between 10-20 applicants… So it’s important to stand out.
There 1 individual interview. 2 individual exercises, and 1 group exercise. They are created to find out DISCOVER, DISRUPT & DELIVER qualities (the telefonica values)
The individual interview is more of an “informal chat”… The interviewer will probably ask the normal competency questions (think, “give me an example of when you have changed someones mind” or “give me and example where you have made a mistake and how you have learnt from it”. They’ll also probably ask general questions like “why do you want to work for O2?”
The individual exercise is where you are given a case study type thing… You will have 25 mins to read it and answer 5 main questions. Make sure you manage your time well and read through all the info. You will then present your findings to an assessor, and they will ask you a few extra questions you weren’t prepared for. This is the DISCOVER part of the day.
The next individual exercise is similar format to the first. Although they will be looking for DISRUPT qualities.
The group exercise is their chance to find out DELIVER qualities. Make sure you speak up… Although often some of the loudest candidates aren’t the best ones!
