If you want to know what really good design is, then do a test assignment, and if you succeed, you are lucky—you get an opportunity to work with art directors who set the highest possible bar. Such an approach will force you to reject the first couple dozens of ideas, but this is the way to get to the solution that will make everyone go, «Wow, didn’t even know that was possible».
And it also comes with a nice bonus — you get to practice your English. Within the product design department, projects are discussed in the language of the industry. It is like working with best chefs de cuisine: throughout the world, they speak only French.
