It says right in the text on this page that "Elauf never told the company she wore the hijab for religious reasons and would have to wear it at work." So it looks like she set them up. Taqiyya.
If she didn't wear it to the interview, she must have intended to give a false impression. If you lie on a resume, you're toast. Why should this be different?
If you can not-hire a person with gang tattoos on their face, you can not-hire a future terrorist who wears a rag on her head.
Were it me, I’d just never have called the terrorist back. Never responded. Made a memo-to-file her interview was lacking and let it go at that.
Taqiyya indeed.
