ASDA interview questions in Leeds

Applied online and received a phone call asking to go into the office for an interview in Leeds. Within the same week of applying I was interviewed, and they asked for a SWOT analysis of specific asda departments. Very quick turn around, the experience was positive until I was told I would receive a phone call if I was successful/unsuccessful , and I received no email reply or phone call, and a generic unfortunately you were unsuccessful email two weeks later. I was really disappointed with this as I had taken the time to go and interview and create a SWOT analysis, to not even have a phone call or email reply.
