Case Study: HackerRank achieves reliable virtual interviews with Zoom Video Communications' Video SDK for Web

Hiring developers virtually is hard; HackerRank uses Zoom’s Video SDK for Web to make it easier

HackerRank, a platform that helps companies evaluate and hire developers through virtual skill assessments and remote interviews, was struggling with unreliable audio and video in its Interview product. As usage grew, 40% of its NPS feedback and many support calls were tied to quality issues, especially during network fluctuations and live interview sessions.

HackerRank implemented the Zoom Video SDK for Web from Zoom Video Communications after testing multiple vendors. The solution delivered more reliable audio and video with the scalability needed for growth, helping support a strong candidate experience across 500,000 interviews in 2021.
