Hi chk180182
If you look at the guide to PIP Claims and Reviews you will find the types of questions that they will ask you at an asssessment. And yes, there will always be a curveball question that appears to have no relevance. These can really vary, but often refer to things in the past, such as "What was your last job title?" If you get a question that you think is a trick, take a drink of water, ask them to repeat the question or simply "I can't remember."
I hope it goes well for you.
