@zwebtiai @ycombinator @trysaffron @roblukan @kazumachoji absolutely. it's hard to know if AI is making you faster, or just making your job easier. experienced devs thought they were faster when they were actually slower. an objective test is the only way to know! see: arxiv.org/abs/2507.09089

@ycombinator @trysaffron @roblukan @kazumachoji @_mjyao most teams still hire for raw coding speed when the real question is: can you ship faster with AI than without it?

Are you missing out on the next 10x engineer? Saffron (@trysaffron) lets companies evaluate how well software engineers code with AI tools. Congrats on the launch, @roblukan, @kazumachoji and @_mjyao! ycombinator.com/launches/Q5b-s…

@ValerianWaters @ycombinator @trysaffron @roblukan @kazumachoji exactly how we felt.

@ycombinator @trysaffron @roblukan @kazumachoji @_mjyao Testing how devs prompt is way more relevant than LeetCode at this point.

find your next 10x engineer today!

being good at guiding AI agents and having insane product intuition is crucial. those are the 10x engineers you want to hire.

90% of SWEs use AI to code now. solving leetcode-style questions doesn’t translate to the job anymore. so what signals should companies look for instead?

Sierra just killed the coding interview. Every engineering team that hasn’t caught up is about to look very out of touch
