Hiring biases , some hidden , some by design...

WHILE YOU RESIGNED TO DESNTINY, THEY MOVED YOUR CHEESE!

Will it be blasphemous if I told you, that HR hiring is caste, language, and regional bias-infested?

I see semblance of this bias, or rather conspiracy around, and it's not new!
But is this alarming, and should this put anyone to shame?
To me, it sounds just not blasphemous but illegal by all standards!
Sample this: This is from one of my previous employments.
A senior person joins from a "firm", where he spent 24 years. He refers one senior HR person, she gets hired. Pat brings two of her ex-HR colleagues in.
One Associate Director gets hired for recruiting; he brings two more through reference.
You may ask what's wrong?
Well, wrong is that you hired for convenience and even followed caste, language and religion and state domicile bias. How fair was your job adverts for these roles? Pure hogwash, right?
A Singapore based green energy company has advertised Head of HR for Bangalore. I went and searched, their HR folks, 3 people at senior levels out of total 5 folks in HR at Bangalore, Delhi and Pune. 3 of these seniors have Bengali surnames. One of these HR leaders shared a picture and post on LinkedIn of a team building training. The trainer has a Bengali surname..:(
CEO sits in Singapore is an Indian. He was seen receiving award for Great place to work in Singapore. He is surrounded by ten other people (from HR), all of them are women and of local origin by looks.
A trainer from God's own country shares LinkedIn post with pictures of his training program at a French MNC. CHRO of that company in India is from God's own country...
I know, I am not alone, who is noticing such things.
Question is, is it some well-designed conspiracy? Are some regions with certain affiliations, more communal than others. What happens to hiring governance?
From God's own country, a man starts a recruiting firm. That gets acquired by a Sweiss firm. He creates a copycat, that gets acquired by a travel company. So, what's the problem here?
Here is a little problem. Go back and check, the M&A consultant if from God's own country, the Head of India for that MNC travel company is from God's own country....What's happening here?
Above cases are just random cases of biases that often gets unnoticed...
CHRO is India's 3rd largest Pharma company, some 6-7 years ago hired most of new HR leaders from his previous companies, one after that other, despite that, he talks about Governance and ethics today...
Honestly speaking, if AI can detect these hidden yet so brazen biases through some "forensic" measures in companies, we will have skeletons tumbling out of cupboards of the corporate's fake Gods....
Final Q- Have we given the keys to our ethics and governance to the thieves?
I personally find with experience, that HR hiring is most biased and corrupt, and I can produce all data and evidence.
