I am fortunate to intern within the department of ComIn, that includes Visual merchandising, Communications, and actual Interior design units. This means, helping as a filler for anything urgent needed is pretty much what my internship witholds.
Communications covers all visual communications: signage; walkways, pricing, shelf info, walkway guidance, sales promotional printing materials, you name it. While the Interior design department naturally builds all displayed room settings, it also takes care of the interior-related functions in spaces for the customers (restaurant, bistro, first-aid rooms, bathrooms), for example lighting, seasonal vignettes, seating, etc. Third part of the department, Visual merchandising, takes care of all short-term and seasonal subjects, starting from displaying basically all items for sale to decorating seasonal podiums, and physically building the racking, sales spot locations prior displaying the items.
Due to seasonal weight of IKEA sales highlighting to the end of the summer as the yearly catalog comes out in the end of August, all refreshed and new podiums and displays have to be finished prior the publication of the catalog. Thus, my internship was already projected to concentrate heavily on helping the Visual merchandising team with building the completely new display sites that are deadlined to finish by the first week of August. This is also what the first four weeks indeed included in June.
