Primark Retails Assistant interview questions

Watched a film about primark and its work for half an hour then went into an induction speech which told you more about the job re rudiment process , had a one on one interview after that which lasted 20 mins . This interview was for a new store opening in Edinburgh , I received a reply email with in 5 days and accepted position

I first applied online and I got a response the next day. I got called for an interview the next day at short notice with an allocated time. The person who called me was very rushed with his conversation, asking if i was still interested and available for the interview, which i said yes. I arrived at the interview with about 35 minutes to spare and was sent to wait in the canteen. As i was early, the interviewer came in saying the name of another lady who also had an interview, however she was not there so i assumed she was late. He then decided to invite me inside to have my interview extra early which i was not prepared for because i wanted to calm down a little bit before i went in. All the things i revised for and the questions i practiced for was asked, except one where i took an extra long pause and didn't actually have an answer to. Then i was asked to try to sell him an item - This was the part where I thought i failed the interview in an instant. As it was my first ever interview, i didn't really know how i would feel after it, but i honestly felt neutral like i didn't feel relieved or unhappy about the interview. He said i would hear back from him later that day if successful or not. I got a phone call with an offer! I was ecstatic.
