Reactjs competencies for candidates
A candidate who wants to apply for a Reactjs open role in your company should have the following skills:
• HTML and CSS: Every Reactjs developer should know at least the basics of HTML and CSS. In fact, every front-end developer should base all of their advanced skills on knowing the basics such as HTML and CSS. At this level, your Reactjs developer should know about semantic HTML tags, CSS selectors, flexbox, and the proper use of media queries. You can test all of the HTML and CSS prerequisites with our HMTL and CSS pre-employment tests.
• JSX: Reactjs developers don’t really work in HTML, but in a similar ecosystem on React called JSX. But if the programmer knows how to operate in HTML and CSS, they will also know how to work in JSX, because these are quite similar.
• Git: Reactjs developers should have Git in their developer’s toolkit for storing projects and solutions on platforms such as GitHub and GitLab.
• Redux: This will be the distinguishing point between an entry-level and an experienced Reactjs developer. Redux is a state management library that helps developers work with data in the Reactjs library. Any programmer who knows their way around Redux has mastered the fundamentals of Reactjs.
But technical skills alone are not enough. The candidate needs to have the accompanying values and soft skills to ensure they are the perfect fit for your organization.
The right candidate
When recruiting, the best candidate for the position will have the following skills:
• Good and effective communication: Reactjs developers need to communicate effectively if they want to get anything done. Developers often do pair-programming and good communication is essential for working well with others.
• Analytical capabilities: The right candidate will have an analytical mindset, enabling them to focus on all the ways they can solve a problem or challenge. They will do this by analyzing the problem and looking at all the possible ways they could approach it to find a solution.
• Good time-management skills: Organizations operate to deadlines and it’s no different for Reactjs developers. They need to have good time-management skills so they can ensure that their work is completed on time.
• Learning ability: Programming languages change and they change fast, so if a developer doesn’t constantly learn and adapt, their skills will become outdated. Reactjs isn’t even ten years old.
• Attention to detail: Reactjs developers need to pay attention to the smallest details when writing their code, since even minor mistakes can cause system malfunctions.
• Teamwork: No person is an island and Reactjs developers aren’t an exception to this rule. The right candidate will need to know how to work with others in the team to succeed in their role.
• Problem-solving ability: The perfect candidate will have a “can-do” mindset, where they will observe a problem from multiple perspectives until they find a solution. So on top of their technical skills, the perfect candidate should also be a good problem-solver.
• Accountability: Reactjs programmers need to own their code and, as such, be accountable for their actions. Accountability is a great personal trait since the candidate will be aware of their responsibilities and make sure they don’t fail.
A practical way to see if candidates have the above skills is to use a Reactjs coding test. With pre-employment testing, you can evaluate applicants’ skills and focus on interviewing only the candidates who are best suited to the position.
