ASDA interview questions

I applied online for a temporary position and received the next day the email where I was invited to an Asda group interview ina week time. At the interview we were 12 and it took around 2 hours. At first we all waited in the kitchen until all the 12 were present. We then went to the meeting room were 6 employees were making observations on us and the manager told us a bit about him and Asda in general. Everything was very informal and relaxed. We were told that if the interview was successful someone will call us in 3 days time otherwise you will receive an email in 7 days time. After 10 day I didn't received none.

Application I applied online. the application was pretty simple -mostly common sense. I then go sent an email from Asda telling me that I should attend the asda magic event. I interviewed at ASDA and was told to wait to give my identification -so that it could be photocopied. 5 mins into the interview I'm told that the role is seasonal -despite not applying for any seasonal jobs...
