I worked for company "A" in the summer and had to turn down another company "B". I told "B" that I have issues at home. They were okay about it.
Now they got back to me, offering me a winter internship.
I was just wondering whether they will find out that I worked for "A" through my NI number. Is that possible? And do I need to give them my P45/P46 form ?
who are introverts?
