I had an assessment centre for the talent and rewards graduate scheme a couple months ago, but I would imagine many of them are similar. Here is how the day went:
Presentation about towers watson and the graduate scheme
Competency interview - half behavioural questions and half motivational questions, eg. Why Towers Watson, what do you know about the day-to-day work of consultants, etc. Lasted for ~45 min
Case study - this was quite difficult, and pretty much everyone in the group struggled and didn’t finish. We had to act as a consultant and analyze the compensations and benefits scheme for a fictitious company. It was very quantitative, and basically we needed to calculate the total value of the rewards package for a couple executives. There was also a qualitative question about the advantages / disadvantages of the current rewards scheme and any recommendations we had for the future.
Group exercise - we got about 10 index cards with random inventions over the last century and we had to prioritize how each of them had contributed to society today (eg. electricity, wheels, computers, credit cards, etc.). They said in the feedback that they were looking for strong collaboration as well as innovative thought.
Problem solving interview - this was divided into two parts: 1) technical questions about talent and rewards 2) brainteaser questions.
For the first part, there were six questions about talent rewards, and we needed to pick two to discuss with the assessors. We were given 15 minutes to prepare our answers. The assessors came back and asked for my response to each question, and then asked some very challenging follow-up questions and scenario questions.
I personally struggled with the second part, as I had never done a brainteaser interview before. The questions I had were:
-how many people pass through London Heathrow airport each day?
-how would you explain facebook to your grandmother?
-how many fries does mcdonalds sell per year?
For each one, we had to get up and work out the answer on a flip chart. I had a particularly difficult assessor, who questioned every single one of my assumptions. I would recommend practicing these questions in a role-play before the assessment day, as it’s much easier doing it independently at home than in front of someone.
Best of luck
