One can find plenty of graphic design job openings on every job board. We typically apply for many of them, or at least for a few, trying to increase our chances of getting some interview invitations. Having said that, you should not leave this kind of an impression in your interview.
Recruiters are proud of their companies. You should convince them that you care for the particular interview with them, that their offer stands out from other job offers.
Do your research
They may use alternative questions. Why do you want to work for our company? Why not one of the competitors? Questions may differ, but they follow the same intentions every time. You should do a pre-interview research and find something that differentiates them from their competition.
Visit their website, check their portfolio, read about their values and goals. You should find something that’s worth mentioning in your interview answer.
Your job description is designed exceptionally, in both graphics and wording. One can see that even an HR person from your company has a creative mind. It signifies that this is the company where one can grow as a designer, at least in my eyes it does so. The list of working duties also stands out. Brand building is a field I would really love to work on.
I spent a lot of time on your website. I saw the work you have done, and I really liked the deign you made for client ABC, as well as the campaign you created for EDF. I have seen countless portfolios before, but I believe you are one of the most creative companies involved in this niche. That caught my eye on your offer, and I would be proud to work in your company.
