Add your answer

Heads Up! HR sent you a design project as homework. It's this whole dashboard thing with custom stuff. But here's the catch:

It's basically free work for them. They get to use your design without any consent from you. Basically, they're trying to get free design out of you. At least they could give us feedback, as we have spent hours doing their assignment. If you do it, remember:
