The key to behavioral interviews is to walk in knowing the 5 or so stories about yourself that you want to tell the interviewers. Just use the behavioral questions as an excuse to hit your points.
so in other words ...
the bw did not have something against you, and the only way her race played a role was in her knowing she had to actually work and do the job well to maintain her position and ended up being negatively characterized possibly by stereotypes
whereas the white guy just sat back doing the minimum and still came out like a white hero?
Well I know she didn't have anything against me just jitters. You know how you answer a ? And it don't come off as believable.
