How to assess Perl Developer skills and traits

Assessing the skills and traits of a Perl Developer can be a challenging task. It's not just about knowing the syntax; it's about understanding how to apply it effectively in real-world scenarios. From Perl proficiency to debugging skills, and from database management to web development, there are multiple facets to consider.

Traditional resumes might list qualifications, but they don't provide a clear picture of a candidate's practical abilities or how well they fit your specific needs. Skills-based assessments are a reliable way to gauge a candidate's competencies. For instance, Adaface on-the-job skill tests can help you achieve 2x improved quality of hires by focusing on real-world tasks and scenarios.

When assessing a Perl Developer, it's important to evaluate their familiarity with CPAN, their testing skills, and their ability to integrate APIs. These are just a few of the key skills that can make a significant difference in their performance. By using targeted assessments, you can ensure that you are hiring the right talent for your team.
