Some employers are stricter than others. Some people don't think tattoos look professional along with body piercings, and others don't seem to care about it. So it depends what the interviewer might think of her depending on their policies and rules.
But for the first interview I would suggest that Tanisha wears clothing that doesn't cover her tattoos so if they have a problem with it they can tell her straight away and if they don't then she can go on and work without worry instead of hiding them and then later on they find out and fire her.
Hope this helps,
Davinia.
