What if I decide to teach you something about the Quran and you don't hire me?
Perhaps this is just urban legend but from the stories I've heard hiring for FAANG-type companies there are people out there interviewing with their only goal being baiting you into a topic they can sue you over.
Worst instance I have heard of is when an interviewer asked about the books the candidate liked to read (since the candidate said they're an avid reader in their resume) and he just said that he liked to read the Bible. After not getting hired for failing the interviews he accused the company of religious discrimination.
I'm by no means an expert in US law and don't know the people this happened to directly so maybe it's just one big fantasy story but it doesn't seem that far fetched that
- If you are a rich corporation then people will look to bait you into a lawsuit
- If you give software engineers (or any non-lawyers) free rein on how to conduct interviews then some of them can be baited into a situation that the company could be sued over way more easily than a rigid leetcode interview
I think nothing came of the fellow who liked reading the Bible but I would imagine the legal department has a say in what kind of interview process a rich company can and can not use.
