At the open days when application forms were given out, they said the interviews would be the last week of July and first week of August. And you had to be able to attend interviews in those weeks in order to stand a chance. The job then starts the beginning of September in the new store before it opens a month later. Check-out operators would start in other stores but come back to New Brighton in time for opening.
I am surprised at a rejection letter coming so soon before the closing date of the Friday, sorry to hear that.
As for ASDA, the jobs for the new store haven't yet gone live, but the Netto conversion stores are advertising under Asda as that is the next phase to open.
