Some of the most successful blacks in tech had to 'hide' their blackness to achieve success. Robert Smith, the wealthiest black man in America, specifically didn't put up a photo on his investment firm's site to avoid any possibility of bias (now that he's a multi-billionaire who's "made it", this is no longer a concern). Calendly, who's CEO is black, and is one of the top performing black led tech startups curiously…
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.
