<p>There is no formal dress code but I doubt they would hire you if you have blue hair and facial piercings. If there is an interview, I would take out your piercings. The hair is not as big a deal, but why take the chance? Once you get the job, then you could put them in again (although your boss may say something.)</p>
<p>Also, it really depends on your piercings and how extreme they are.</p>
