The - to my mind - most absurd version of this was a well-known Swedish fintech I interviewed with where the one barrier they had set up was one of those online IQ tests (rotating, mirroring etc. blobs on a grid).

I was interviewing for a senior data science role and the other points of contact I had in the process were surprisingly non-technical conversations with a VP of data and another senior data scientist.

Alas, my skills in rotating blobs on a grid failed me that day so that was that.
