Your assumption that the room was full of men and one female recruiter perpetuates gender inequality as much as your assertion that everyone should refrain from good natured ribbing at ridiculous requirements just because the person dictating the requirements is a woman.

Gender inequality in tech is a much deeper issue that starts much earlier in life. And it's possible the ridiculous requirement of 12 years of kubernetes itself perpetuates the issue because it immediately preferences people who came up with the OG attitude.

Although I suspect that may be bait, when you look at everything from that perspective everything looks gender related. Just because they hired a woman to do the job has nothing to do with it.

Tribalism around gender, race, nationality etc. serves only to divide us into smaller and smaller groups.
