I feel for you and anybody who is overlooked when quite clearly capable.
As a white working class child in our East London, UK secondary school, growing up on the Council estate, we were often picked on or overlooked by teachers back in the 50's/60's . We were beaten regularly. Later, with minimal qualifications, I was ridiculed by employment agency staff for not having the exams behind us or a university degree those people thought it was easy to get.
That was back in the days before immigration opened up in the UK but I guess that just pushed me up the chain a notch.
It is easy to get angry about injustice and inequality whoever it is affecting and made me into a Labour Party activist for a while. I did eventually overcome society, by a combination of lies, tampered CV's and my own nous to become a successful company owner and project manager on many international contracts. But I had to get out of the UK to do it. To get away from our class riven society, where the old school tie rules.
Believe it or not, it was American companies that promoted me, once I was experienced in my industry. They took no notice of my Cockney accent and assessed and awarded me a degree in Engineering Management.
Now a 74 years old and I'm still fighting the system's ageism. There is always a battle if you're a fighter.
I guess it is even harder for a black woman in the USA, but I actually feel that a well educated American black might fare better in the UK than me. The awe in which go-ahead Americans are held might work here.
I do so wish you the overwhelming success and happiness you clearly deserve.
