I applied to a certain scraping fintech in the Bay Area around 5 years ago and was asked to open the Wikipedia page to k-means squared clustering and implement the algorithm with tests from scratch. I was applying for an android position. I still laugh thinking about how they paid to fly me out and ask such a stupid interview question.

I see how it might not have anything to do with usual Android development, but why do you consider it a stupid question?

K-means is not that complicated and naive implementation with e.g. Euclidean distance is a couple of dozens of lines of code, so should be practical enough for an interview.
