If you've ever worked closely with good copywriters, you'd find that they always care.

Care for the brief, the insight, the campaign plan, the design, the media budget, the client, and their customers.

Apart from craft and story-telling, see if the copywriter you’re looking at gives a damn.

And if they tell you that they do, then don’t take their word for it. Instead, look at their work. Chances are that it will show.
