Hard to believe this is still happening.  A team asked RB Derrius Guice if he likes men.

It’s a question that keeps getting asked of incoming players, regardless of how many times the fact that it was asked leads to a supposedly increased awareness regarding the importance of not asking questions like this. Two years ago, cornerback Eli Apple faced that question in a pre-draft interview with the Falcons. The NFL dubbed the question “disappointing and clearly inappropriate,” and the league vowed to look into it. Three years before that, a team asked tight end Nick Kasa if he likes girls. The league dubbed the topic impermissible and said that persons asking such questions would be subject to discipline.

Can't imagine another place of employment where this would be tolerated in screening interviews.
