@croydon - Yeah, you can't just join a big business and expect your visual merchandiser career to involve creativity. Often the stores are identical, because they did a lot of research on what is the optimal display type.
As the visual merchandiser, your job would be to follow the instructions sent by headquarters.
Of course, it's not like that everywhere and smaller companies aren't going to worry all that much about looking like clones.
And there are plenty of virtual merchandising roles that involve a lot of creativity these days, but you need to know your website design if you want to get into that.
