Top 6 technical assessment tools to vet a ReactJS Developer

According to Stack Overflow’s 2021 survey, React is not only the most extensively used web framework this year but also the most wanted, desired by one in every four developers. Moreover, 8000+ companies, including Instagram, WhatsApp, Yahoo, and Dropbox, are empowered by ReactJS. With the demand for ReactJS visibly growing and the talent pool limited, it’s no surprise that a successful recruitment drive may require external assistance. It can be time-consuming and difficult to vet developers by yourself, therefore, tools to vet a ReactJS developer comes into the picture.

Some of the significant challenges hiring managers face while vetting include – 

  • It is time-consuming to find an excellent ReactJS developer
  • We use our ways to vet developers, unaware whether the vetting process is correct or not? 
  • Finding better alternatives to technical assessment tools available on the market (especially when you are new to this)

Keeping this in mind, we have curated a list of the top 6 tech assessment tools to vet a ReactJS Developer meant explicitly for conducting technical tests.

These tools have been compared based on the following criteria:

  • Types of Coding tests
  • Duration of the tests
  • Ratings
  • Set of predefined libraries
  • Qualification criteria for the candidates
  • Differentiating factors
