Discussion of hiring practices and underrepresented groups during interviews
Discussions about how to improve participation from underrepresented groups in academia are not uncommon in interviews, even when the interviewee does not come from such a group.  That a department has a strong commitment to hiring people from underrepresented groups is an important thing for the interviewee to know about the department.  After all, if the interviewee is hired, they are going to be expected to be part of the departmental team that is working toward broadening participation.

If you are interviewing for faculty positions and are not part of an underrepresented group, it is still a very good idea to have thought carefully about the underlying issue.  When the issue comes up in an interview, you should be able to voice your support for broadening involvement in your field.  You should also have some specific thoughts about why this in important and, most crucially, how you can help.  Hiring you may not represent direct progress toward the goal, but you have an opportunity to show that you are enthusiastic about recruiting students from underrepresented groups and working to hire people from those groups when you are part of the faculty.
