Hey good idea, deliberately exclude people who don't eat meat. You know who might end up being CEO level material
If you are a hiring manager and you are attempting to learn someone's religious or dietary beliefs prior to hiring then then you should be sued/fired.
And yes when I've taken my candidates for lunch as part of recruiting I always ask for any dietary preferences so i can find a place that accommodates. It's just commonsense.
Keep in mind that they missed out on Forstall. It seems unlikely he would have ended up CEO, but that’s not as far fetched as the prospects for most hires.
