We aren’t, and we don’t. You are misinformed.

In Britain, the word ‘biscuit’ means a hard baked cookie, like a graham cracker. Since this is the normal use of this word in the UK, we don’t automatically think of the plain scone-type baked goods for which Americans use the word ‘biscuit’. US English is a different dialect of English, and there are many words which have different meanings from U.K. English (jumper, braces, suspenders, tap etc.)

What on earth makes you think we call bread rolls ‘puddings’? In the U.K., pudding is any dessert, not just the blancmange-stuff which Americans use that word for. It is correct in the U.K. to say “I’m having apple pie for pudding.”.

I’ve also ended interviews as a candidate on the phone myself. They asked a question that I didn’t’ have the answer to and I told them that I didn’t know. The next 2 questions were in that same direction, with them knowing that I’d already said I wasn’t particularly fluent in that area but they kept on. At that point I said, “Let’s just stop here. We both know that I’m not doing well answering your questions and to be honest, that you’re restating the same topic after being told that already I don’t know probably means we wouldn’t be a good fit.” Too many people forget that it’s a two-way street and they seems shocked that anyone would actually end their interview.
