Interview was about hour long and took place at the site I would be working. Was asked various questions and was then explained to me how the company worked and hours. I was shown round the site I would be working at and was talked through what I would be expected to each week in the 2.5 hours a day I would be there. I was also asked if there was a cleaner off would I be able to cover for them. Was offered the job there and then and started the next day.
