Very informal. After I’d applied online through Indeed/their website, it took 3 months to hear anything back. I got a random call from the home shopping manager and was essentially told I’d been hired, what hours could I work etc and then to bring paperwork in on a selected day. Turned up in a polo top, jeans and smart shoes, other candidates barely made any effort and all of us were still selected. Just sat in a room with the group, read over terms and conditions, filled paperwork out, had some videos to watch about health and safety, etc. had a tour of the shop floor and brief discussion about the job role itself.
