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.

HR manager called me and had me do a group interview over the phone, then gave me the date and time for the actual interview and i met with the HR manager there for a first interview. then couple days later called me in for a second interview and then i met with my cash manager for the position and gave me an offer then and there
