and, cards on the table, I will not redact company names because I don't really see the point, these are my experiences not rumours.
Here's two, there's one more but it's a bit too awkward to type out on my phone;
Elastic: there were two Lead SRE positions open, I was recommended to apply, so I applied (friend still works there). I passed the interviews and was offered the job, the other job was filled by someone internal; they rescinded the job offer after having a candidate who was just as qualified but was female. I was offered a position under her. I would have been happy to take the lower position if I hadn't been offered the other one (and accepted) and if it hadn't been on the stated basis that it was because they wanted a woman and that's why, nothing about personality, culture fit, approach or even skill fit.
Ubisoft Massive: I applied for an Architect position (a promotion), I was told that I need not bother applying as the position was only going to be filled when we found someone with a non-white ethnic background, and preferably a girl. This was not long after being told by HR that "my next hire had better be a woman" after hiring a 45+ year old white Swedish guy, so I should have known.

For balance; I'll say that my ethnicity has helped me too once, I got a job at Nokia partially because I was natively English speaking, so it's all swings and roundabouts.
