The papers and open source indicate that you can build stuff. That's not what it's testing for.

Will you put up with very long hours of insane grindy nonsense in the spirit of being a team player for a team that doesn't really remember what game they're playing?

Are you sufficiently in need of income to be fighting through this interview dance in preference to other things, such that once you join you'll be desperate to stay?

Those are extremely important questions, and a willingness to have spent a thousand hours memorising leetcode correlates strongly with the attributes sought.
