The rules at Karat may be that giving any kind of help pretty much automatically disqualifies the candidate, so technically they're better off giving you no help at all in the hopes you make as much progress on your own rather than ruining your interview by giving you help prematurely.

One thing I didn't appreciate with these rules from a candidate perspective (and encouraged my decision not to continue my onboarding with Karat), there seems to be no way to learn from the process.
