I work in tech recruiting, It's 100% your race, gender, sexuality and nationality blocking you. Our ATS/HR systems can sort and filter you by "pipelines" which users label with demographics. Most have diversity features that alert you when you have too much or too little of a certain group. We have constant lunch-n-learns and seminars about how to recruit "for diversity" in a "compliant" way (how to do it illegally without getting caught). We pay NGOs and staffing agencies to hand us resumes from people who are only of a certain race or gender. Our "global mobility" departments get the foreign resumes and we put them first because they cost less AND check off DEI boxes. We put you on blacklists/ignore lists/do-not-hire lists if you arent diverse. And if we don't have that feature, we put it in the "notes" on the candidate file. It is DEFINITELY discrimination. Every straight white American male I've screened was qualified and well-versed for the position they were going for, and every time I was told by superiors to focus on "other pipelines" AKA the diversity hires.
