iMocha’s Live Coding Interview: Alternative to Whiteboard Interviews
Traditional whiteboard interviews, once standard in technical hiring, often fail to replicate real-world development environments. They test problem-solving under pressure but don’t accurately reflect how candidates code, collaborate, or think in practice.
iMocha replaces outdated whiteboarding with a modern, browser-based Live Coding Interview platform. It enables hiring teams to assess candidates in a realistic coding environment, complete with video conferencing, real-time collaboration, and access to a comprehensive coding library.
Key capabilities include:
- In-Built Code Editor: Supports 35+ programming languages with real-time compilation and test case execution.
- Code Replay: Review every keystroke, run attempt, and logic change to evaluate coding approach, accuracy, and code cleanliness.
- Real-Time Collaboration: Invite multiple interviewers to join, ask follow-up questions, and assess collaboratively.
Here’s how iMocha’s Project-based assignments is different from the others.
iMocha’s project-based assessments simulate real work by allowing candidates to complete role-specific tasks in flexible timelines using real tools. Unlike rigid coding tests, they evaluate practical skills, code quality, and problem-solving in realistic scenarios.
This approach delivers deeper insights into a candidate’s job readiness and provides a better experience for both recruiters and candidates compared to CodeSignal and HackerRank.
