Tesco In-Store Assistant interview questions

It was many years ago but Glassdoor require a review to see anything on the site, so please take my info with a pinch of salt. My partner has worked for two different Tesco stores and didn't have the same interview experience as me. The interview was ok, but I was asked an 'if you were a biscuit...' question and absolutely hate those types of questions. You can't even answer them in a work-type way (maybe "A rich tea, because they're reliable" or some crap) I didn't get the job so perhaps they sensed my bad vibes.
