I thought it wise to try this strategy when looking for employment, but I think it actually works against me in that case. If the employer knows I'm black then they can filter me out from the get-go and save both of us time rather than be dragged through a pointless interview process. It's hard to really quantify the exact degree to which my race is a detriment to how I'm perceived, but I sense it often enough to know that it's there in some capacity.
