How to assess Typescript Developer skills and traits

Assessing the skills and traits of a TypeScript developer can be a challenging task. It's not just about knowing TypeScript; it's about mastering JavaScript, understanding front-end frameworks, working with Node.js, and more. You need to ensure that the candidate is proficient in version control, familiar with testing frameworks, and capable of seamless API integration.

Resumes and portfolios can give you a glimpse of a candidate's experience, but they don't always reflect their true capabilities. To get a comprehensive understanding of a candidate's skills, you need to go beyond traditional hiring methods. Skills-based assessments, like those offered by Adaface, can help you achieve this. These assessments can lead to a 2x improved quality of hires and an 85% reduction in screening time.

By leveraging targeted assessments, you can evaluate a candidate's proficiency in TypeScript, their mastery of JavaScript, and their ability to work with front-end frameworks and Node.js. This approach ensures that you find the right fit for your team, someone who not only has the technical skills but also the practical experience to excel in your specific role.
