I already had an in, because I have family working for the company, so my interview process was significantly shorter. They called me and conducted a short interview to assess if I had the attitude they were looking for in a coworker. I came in a few days later and met with an HR associate and the store manager to further get an impression of my attitude and personality. A few days later I came in again to accept the job offer and find a position that suited me, as there were a few open positions. I came in once more to take the drug test, a mouth swab, and they told me the starting pay rate. My first day started not long after. About 2 weeks had passed since initial contact.
Everyone was extremely helpful and nice, and any nerves I had at the beginning of the process were gone when I met the HR rep and the store manager. It's a bit confusing because of the strong Swedish culture, but you get used to it pretty quickly. There are a lot of international coworkers, and a surprising amount are actually from Sweden. It's clean, you have a staff cafeteria, and you learn to negotiate the large store with surprising ease.
Just go in and be confident, friendly, and keep a few fun and interesting stories in your pocket to show the interviewers a bit of your personality, because they're not looking for mindless drones, they want nice, interesting coworkers that have something to add to the overall store experience.
