I didn’t think Canonical did IQ tests, they just wanted you to report your high school GPA and class rank, and list all the clubs, activities, and awards and great things you did in high school and college. Even if you’ve been in industry for 20+ years.

Back in 2018 Bullhorn ATS tried this on me, and even asked me to retake it because the recruiter said “you didn’t score high enough” despite passing the actual interview.

Could have been Coinbase. They make you do a "cognitive assessment".
