HackerRank

Change the world to value skills over pedigree.

How easy is it to cheat on an AI interviewer, really?

Our CEO - @rvivek thinks he’s got it figured out.

Let's find out 🍿

[HackerRank @hackerrank]

The last edition of @hackerrank Orchestrate was a movie 🎬

A record 5,500+ builders from around the world, with over 350 of them building alongside us at our Bangalore office.

Fun fact: our oldest participant this time around was 50 years old and our youngest one was just 14! Talk about range.

A huge thanks to everyone who participated, and congratulations again to all the winners.

Okay, this is very exciting.

Sunny, who finished #1 globally in the September edition of @hackerrank Orchestrate, has officially joined us as an AI engineer.

He competed in 3 editions of HackerRank Orchestrate, finishing #42 in June, #15 in August, and #1 in September.

Super impressed by how he kept showing up and improving with each edition.

Most importantly, he demonstrated a critical skill developers need today: the ability to orchestrate AI agents to craft compelling solutions.

What does interviewing with Chakra actually look like?

Here’s a walkthrough from the candidate’s POV.

[rvivek @rvivek]

Hiring has changed. It's not about what you can build. It's about how.

With AI, you can build software, compose music, write articles, and more. The output is no longer the hard part (although the quality varies), how you got there matters more.

We have reimagined @hackerrank and are continuously raising the bar on helping customers hire for the agentic era.

Here's a wrap on our fall release 🧵

Hiring in the agentic era means looking beyond just the final output and understanding how someone got there.

Now that AI has made it easier to build, evaluating the approach matters more than ever.

Here’s what we shipped @hackerrank this quarter to help you do that.

If you walk into the @UseCorgi cafe and tell them you hate binary trees they bring out this bad boy

This is true. I met Garry yesterday after a really long time. He saw me pitch the new hackerrank and sent a text that simply said, “so proud of you bro”.

Little does he know that the text will give me fuel that will last for a few months, if not more to work on even greater things.

People from the outside think about YC as just office hours, some money, community, etc but an underrated aspect of YC is giving founders the belief that they can build something special.

Such a great institution!

Look ma, we made it 🥹

HackerRank Bench just added Gemini 4 Argon to the leaderboard of frontier models on real-world, long-horizon SWE tasks.

Argon scored 49.7% overall, just behind @AnthropicAI's Opus 5.5 and Fable 5.1. It did so at just a third of the cost of Opus 5.5! 👀

Here's where Argon stands out: it tops the leaderboard for greenfield implementation (63%), building working systems from scratch faster and more completely than every other model we tested, including Opus 5.5. It also leads frontend & interaction fidelity among non-GPT models (63%).

Its weak spot: Identity & provisioning integration, where it trails Claude Opus 5 and several others - implementing standards-based identity lifecycle and synchronization across tenant boundaries is still its toughest category.

Every task on our benchmark is original, unpublished, and scored by hand-written behavioral verifiers.

Find the full report with the leaderboard, cost curves, and task-type breakdowns.

We started @HackerRank a decade ago with the belief that skills matter more than pedigree. That’s still our core ethos, but the skills required to do the job have changed.

So, we're tearing down our past and reinventing the company from scratch.

Meet Chakra - the future of hiring.

[HackerRank @hackerrank]
