NEW FEATURE 🎬🧡

New in Hellyeah: video ad support for Performance Max campaigns.

We’re expanding the creative formats you can work with in PMax—and this release brings video into the mix.

Also shipped: a little polish where your team leaves feedback. Author comments now have improved Markdown styling, making formatted notes easier to scan and follow.

Built with the people who keep shipping: @Doudoujay @dralaska_ @anitawu001 @lololalahaoran @YChahahahaAI @lwqconnie @Antiaefuj @MuvaniaJaya @MarcoFerna60597

Most engineering interviews are already obsolete.

And most hiring managers are measuring the wrong thing: résumé prestige, LeetCode speed, and the ability to sound impressive for 60 minutes.

For AI-native teams, the bottleneck is no longer typing. It is judgment.

Can you choose the right problem? Give an agent the right context? Catch a plausible wrong answer? Recover when the data, evaluator, or dependency changes?

My hiring philosophy is simple: start with the 90-day outcome, look for evidence of exceptional ability, let candidates use AI openly, and test whether they can verify and own the result under changing constraints.

Introducing hellyeah/assessment: an AI-open engineering assessment where candidates can use Claude Code, Codex, and their own tools. The proposed workflow gives them four hours to work on a real problem.

We are not trying to detect AI use. We are trying to see what happens around the code: what they delegate, verify, keep human, and stop doing.

Built with @Bharath_uwu, @WilsonTseng8, and @joshualocke100.

The controversial view: the best AI-era engineer may be the person who knows which code should never be written.

What part of the traditional engineering interview would you delete first?

I grew up in china and am now building companies in the US.

The environment for entrepreneurship in each nation is radically different.

I find the US has a very high tolerance for founder failure.

In the Bay, people don't care if you've failed multiple startups. If anything, it's like a badge of honor.

I angel in a lot of YC companies, and many of them will fail. When that happens in the US, the founder shuts it down, starts a new entity, and raises from a new group of investors. Investors buy this narrative of "I tried, it didn't work, let's move on."

Chinese culture doesn't tolerate this kind of failure.

In China, the mindset is closer to "I have to succeed."

Founders keep a struggling startup alive far longer than a US founder would. And if they do start a new entity, the previous investors usually get taken care of with equity in the new company, so it's never really a clean restart.

As someone who has seen both sides, I believe the Chinese approach drives a lot more competition and creates a culture of extreme persistence. It means your team doesn't even consider "quitting" as a viable option. They will do whatever it takes.

Today, I'm building Hellyeah AI. We're a US company, and I like building here.

But the team I want to build is the one that doesn't even think of quitting as an option.
