This proves a lot of things:

1) Python is unreadable.

2) AI companies are content with slop and do not even bother with clear problem statements.

3) LOC and appearance matter, not goals or correctness.

4) Anthropic must be a horrible place to work at.

Well working under someone who keeps insisting Software engineering is dead sounds like a toxic work environment.

"1) Python is unreadable."

Would you prefer C or C++?

"2) AI companies are content with slop and do not even bother with clear problem statements."

It's a filter. If you don't get the problem, you'll waste their time.

"3) LOC and appearance matter, not goals or correctness."

The task was goal+correctness.

"4) Anthropic must be a horrible place to work at."

Depends on what you do. For this position it's probably one of the best companies to work at.
