ASDA Shop Floor Assistant interview questions

I applied a a few days later received a call asking about my availability for the interview. Interview was done by section leaders and they left me feeling very confident with my availability for shift times and saying my answers were great, I was taken around the shop floor and then asked about my notice period. I was informed I’d receive a call after they finish with interviews but almost 3 weeks later and nothing with no response to an email I had sent.
