A critical factor to consider when hiring a graphic designer is whether their work aligns with the overall design aesthetic you envision for your project.

If the designer you’re considering has a portfolio full of edgy, hand-illustrated black-and-white cartoon characters, they might not be the best fit to work with a mature brand that wants to appear authoritative. It's a good idea to look through the designer’s work to get a sense of whether their aesthetic jibes with your vision before getting too far into the interview process, but be sure to ask this question regardless.
