Elite schools do that in undergrad; e.g. as an initial scored lab exercise, write this recursive fractal shape using Logo, parallel Delaunay triangulation with prefix sums , dynamic programming solving oligopoly problem or single-value Paxos pseudocode on a piece of paper in 10 minutes (I am being serious). If you can cope with it, it immediately shows up in the interview and you are considered a member of the club, a person worthy of having conversations with.
For further actions, you may consider blocking this person and/or reporting abuse
We're a place where coders share, stay up-to-date and grow their careers.
I read this on hacker news the other day and it makes me want learn Logo.
