The usual fare: log out, disable biometrics, use long pins and passwords, power off. Prefer a burner device, or clean your device and restore when you arrive.

I remember how Google's internal guidelines for travel circa 2011 required to remove any material under NDA from your laptop when traveling to China or Russia; you had to restore it over the VPN after a safe arrival. Funny that now the same precautions apply to the US :((

"We rewrote this code from language L to language M, and the result is better!" No wonder: it was a chance to rectify everything that was tangled or crooked, avoid every known bad decision, and apply newly-invented better approaches.

So this holds even for L = M. The speedup is not in the language, but in the rewriting and rethinking.

This is a kind of task that's best solved by possibly spending more than the allocated 2 hours on it, once any obvious low-hanging fruit is picked. An optimization task is what a machine does best. So the real problem would be to construct a machine that would be able to run the optimization. A right optimization framework that results from the effort could also efficiently solve many more similar problems in the future.

I understand that this test is intended to somehow test the raw brianpower, the ability to tackle an unfamiliar and complicated domain, and to work under stress. But I hope it's not representative of the actual working conditions at Anthropic. It's like asking a candidate to play a Quake deathmatch when hiring to a special forces assault squad.
