The 20x Developer Is Real (And It’s Worse Than You Think)

You’ve heard of the mythical 10x developer—the one who seems to do the work of an entire team. But what if the gap is actually much bigger?

After running over 500 real-world coding interviews, we found that top-performing engineers aren't just faster—they work in a fundamentally different way. In this blog, we share surprising data, the behaviors that set 20x developers apart, how to design interviews that reveal true skill, and why some juniors are already outperforming seasoned seniors. Whether you're hiring or building a stronger dev team, this will change how you think about engineering talent.
