Parameter 3: Coding Interview Features Comparison

Codesignal, Hackerank, and iMocha are platforms that enable enterprises to go beyond the noise of technical hiring with automated and live coding interviewing solutions. These platforms offer similar services, but a few things set them apart from each other.

iMocha's Live Coding Interview helps you replace the traditional whiteboard interviews

Whiteboard interviews became popular in the early 1990s. These interviews were introduced as part of the technical interview, which tests a candidate’s technical and problem-solving skills. While some organizations still rely on traditional whiteboard interviews to assess a candidate’s technical aptitude—whiteboard interviews may not be the best option today.

Organizations worldwide have embraced the new normal of hiring, i.e., remote hiring. And traditional ways are no longer an option. Hence, organizations are compelled to either modernize and fine-tune them or eliminate them.

And that’s precisely what iMocha did!

One of the most significant issues of whiteboard interviews is that they need to achieve their intended goal: to mirror real work environments. To solve this problem for recruiters and hiring managers, iMocha offers the Live Coding platform feature, a video-based coding environment, to help tech recruiters and hiring managers to assess real-time coding skills in a programming environment.

The features include:

• Access to iMocha’s coding library with over 35+ programming languages and 3000+ coding problems in real-time. The library includes questions based on the difficulty level: easy, medium, and hard.
• An in-built Code Editor with the ability to compile against predefined test cases.
• iMocha’s Code Replay feature will help hiring managers understand a candidate’s code cleanliness, memory optimization, accuracy, and logic. This helps understand the approach of a candidate solving coding problems and differentiates good programmers from average programmers.

Here’s how iMocha’s Project-based assignments is different from the others.

The foremost advantage of iMocha’s Project Based Assessments is that they are a great way to imitate the work done in the company. And unlike an interview situation, where candidates are expected to write code on the whiteboard within an hour or so, they get a reasonable timeline to write code, wherever they want, in the comfort of their homes.

This, in turn, enables them to work exactly as they would while on the job. Hence this provides a better approximation for recruitment teams of their actual performances. It also provides the candidates with a better view of how the job would be. When compared to Codesignal vs Hackerrank, iMocha’s Project Based Assessments provide a holistic measure of a candidate’s abilities and working habits.
