Not through bad intent from folks doing the hiring just through human things: white men are more likely to know what to expect from a tech interview, or even to know someone who can give them an inside scoop. Without even getting into how off putting some job listings can be to many folks not extremely steeped in nerd culture.
The actual interview process everywhere I’ve worked has been pretty rigid and without doing some form of blinding on the code parts could not be more neutral to the candidates identity.
Which is to say: if you’re not getting interviews as an experienced software engineer you must have something glaringly wrong with your resume. Maybe have a trusted friend or former coworker take a look. If you’re not getting offers from at least some of those interviews you probably need to brush up on your algorithms, and make sure you’re actually conversational in all the things listed on your resume.
