A person's faith is immaterial to their ability to do the job. It's not only illegal (at least in the United States and many other jurisdictions) to refuse to hire someone for a religious reason, it's also wrong and it's irrational. As long as they clearly were qualified and were a fit for the organization, I'd be happy to hire them.
The picture is illustrative: a woman wearing a leather jacket with studs and a blouse is not particularly radical. A hijab is not a burqa. It's as much cultural as it is religious.
If the hijab were an inconvenience, such as if it were a safety or cleanliness issue, I would ask that it was removed during work, and would attempt reasonable accommodation through other means. Aside from that, though, it would be wrong to make it an issue.
Companies need to be part of the solution and not part of the problem. When it's possible, they need to stand up for an inclusive and tolerant society.
