Pros
IKEA is a great place to work for in terms of retail. Plenty of opportunities to grow and explore within the company. The employee perks are wonderful as well as the health benefits. Great retirement plan with 401k options. They strive to keep their employees happy since a happy worker is a productive worker.
Cons
Although the concept of IKEA is grand and wonderful, at the end of the day you are working with people who see it as just a job. Neither them nor the management see the IKEA ideology and do not care for it. The benefits are great, but the pay isn't. I guess it depends on which department you work in and your rank (HL1, HL2, HL3, Team lead etc.). Depending on your superior(s), you will either enjoy your experience or it will be hell. Also, it is hard to plan your life around random days off.
