Why do companies switch
from HackerRank to Triplebyte Screen?

"We use Screen because it's free and it's better.
It gives us real signal on skills where other tools don't."

Patrick O'Grady // VP of Engineering at Ava Labs

Why Triplebyte is
better than HackerRank


Highly predictive of interview performance

We build Triplebyte assessments using data from interviews at 1,000+ companies. Because they're trained on real hiring outcomes, the assessments are highly predictive of which candidates will do well in your process.


Build a custom test in 2 mins

No scrolling through 1,000+ questions. Just choose the exact skills you want to test for and send the test. It’s that simple.

Skills you can test for:

  • Front-end
  • Back-end
  • iOS mobile
  • Android mobile
  • DevOps
  • Dev Automation
  • Distributed Computing
  • Linux CLI
  • Algorithms & Data Structures
  • Coding Logic
  • Java
  • JavaScript
  • Rust
  • Go
  • C++
  • C#
  • SQL
  • React
  • Machine Learning
  • Data Warehousing/ETL
  • Apache Spark
  • Data Science


High Completion Rate (> 80%)

Triplebyte tests are low-stress, adaptive, and can be as short as 15 minutes. Over 80% of applicants complete the tests they receive, which is 2-3x better than typical coding assessments.

Why they made the switch to Screen

About Ava Labs

Ava Labs is a distributed global blockchain company. Patrick O’Grady, VP of Engineering, leads the engineering team of 45.

Prior to the switch

Ava Labs was a paid customer of HackerRank with several licenses. Hires weren’t happening fast enough and the team was spending time on interviews with candidates who did not meet their technical bar.

Testing out a new test

Patrick looked for other options. Since Triplebyte Screen is so short and free to use, he set up an A/B test sending both HackerRank and Triplebyte to every candidate. He ran the A/B test on more than 100 candidates, and saw clear results.

Switching was a no brainer

Triplebyte Screen

“I quickly found that the HackerRank signal was awful. People could score 20% or 80% and you still have no idea how good of an engineer they actually are.

But the Triplebyte Screen scores gave actual signal. Now, our 25 minute Triplebyte Screen is our bread and butter. We’ve sent out over 200 tests in the last quarter, and it’s the most effective tool we have to cold evaluate engineers.”

“If they score a 4 or 5 on Screen,
we make an offer 50 to 60% of the time.”

Triplebyte Screen is accurate, easy to use, and free.
