In India, there is a selection test happens for schools called JNV[1]. These are schools designed for talented underprivileged kids who grew in mostly rural areas. The selection test actually uses this format of pattern recognition to judge abilities of 10-11 years old kids.

I thought that’s pretty neat given how universal pattern recognition is and it helps remove bias from selection process towards kids who can’t afford extra classes to pass the exam.

A decade or so back my son applied for one of the few remaining state selective schools in London. About 2000 applied for 100 places. Admission was by similar tests, including verbal and non-verbal reasoning. Despite the claims you can't game these tests, many people use tutors. We didn't, but I bought him all the non-verbal reasoning papers I could find online. He practised a lot, and over six months progressively raised his mark from around 70% (not high enough to get in) to 100% on the final practice paper he did a couple of days before the entrance exam. I'm sure you need some native aptitude, but it's not at all clear to me these really help remove selection bias.

My son told me that when a new teacher gives them a word-search or visual puzzle, they kids will have finished before the teacher has finishing handing them out. On the other hand, he also tells me common sense isn't so common there, so things do tend to balance out in strange ways.

Yup. New York has a gifted and talented test that's supposed to require no preparation, but kids are competing with other kids who have spent time/effort/money to prepare: https://www.amazon.com/s?k=new+york+gifted
