Sharon… I know what you mean. Passed that stage now, so on the AC.
I spoke to my lecturer and she advised me to get books regarding competency questions and have positive answers ready. This is common sense but having the book or other material might help you think of some you would never have thought of on your own.
I’ve done a few assessment centres in the past few years and my only advice don’t quote me as this could be different is to be relax and yourself. It will come across easily in the group interview. But really good luck everyone
