Primark Retail assistent interview questions

I filled out a short application form online along with my CV. Got a call a few days later and was asked to go in for an interview. Interviewer was friendly and I felt relaxed after a few minutes of talking. Was asked to describe my skills and experience and was then asked a few standard interview questions.

Very straight forward. You first Meet a supervisor, who will ask you for your passport and NI number, then you are asked to fill in a form with your details and your preferences about the time you would like to work. At last the supervisor will ask you 5 simple questions such as why did you apply for this job or tell me about a previous experience where you had to solve a problem
