IKEA Cashier interview questions

I filled out an application for the cashier position online. I got a call from the department manager asking me to come in for an interview. The lady I interviewed with seemed very nice, and asked me basic questions. It went fairly well. She let me know that she or her manager would be calling me back for a second interview. A couple days later I got a call for a second interview. It actually wasn't an interview at all; they just let me know I got the job, went over a couple basics, and did an on-site drug test.
