Market research evaluates and segments the worldwide developer population at 24.5 million. This number is estimated to reach 28.7 million in the upcoming years. Moreover, with the great migration, there is no dearth of candidates, but finding the right ones for you can still be an uphill task.

There are various reasons for it, but some of the crucial ones are:

  • Lack of formal education while hiring for niche skills – for various skills like Ruby, NumPy, AWS, etc. there is no formal education, and recruiters often have to rely on resumes
  • Lack of focus on soft skills – for technical roles, often, recruiters forgo soft skills assessment
  • Competing offers – developers are in great demand, and they often have competing offers from various organizations, leading to stiff competition

So, in this challenging environment, recruiters and hiring managers have to rely on developer assessment tools to get a complete report of each candidate’s skills. They not only delineate strengths and weaknesses but also how your candidates will fare on the job.

And to make the process of selecting this software easier for you, we’ve created this comprehensive list of developer assessment tools, replete with their pros and cons, pricing, and more, so you can make an informed decision.

Note: All the pros and cons included in the listicle are taken from verified sources like G2 and Capterra.
