I went in and basically just had the job, i filled out paperwork, there was never a real interview, more of asking when i could work and where.
First I went in as a part of a group and filled out everything i had done online again to be sure it was correct, address, age, ect.
Then I was asked to take a drug test and return in a week, I did, and on my return I was expecting to be questioned but no, I simply filled out some paperwork for taxes and was shown some times to work and asked to pick one, had my finger prints taken and told to come back in two weeks.
