NPM Online Test

NPM (Node Package Manager) is basically a package manager for Node.js packages or modules. NPM makes it easy for JavaScript developers to share and reuse code, and it makes it easy to update the code that you are sharing. NPM comes bundled with Node.js installable after v0.6.3 version.

NPM online test is created and validated by experienced subject matter experts (SMEs) to assess NPM skills of candidates as per industry standards. Online NPM test helps recruiters and hiring managers to gauge application skills of Node.js experts for the efficient use of NPM before hiring/recruiting them onboard.

The NPM assessment test helps to screen the candidates who possess traits as follows:

1.  Intermediate proficiency and familiarity with best practices in the following areas: Node.JS, JQuery and Database Objects

2.  Knowledge of JavaScript

The NPM online test enables employers and recruiters to identify potential prospects by evaluating working skills and job readiness. For this reason, the emphasis is laid upon evaluating the knowledge of applied skills gained through real work experience, rather than theoretical knowledge.  Our NPM skills test reports will give a detailed analysis of each candidate and will provide the analytical data which helps you to hire better and faster.

Screen potential hires by using our scientifically designed online NPM pre-employment test. Use intelligent reports to analyze the technical strengths of the candidates and make the right hiring decisions.
