A Node.js developer is an individual who works with other specialist developers to manage the exchange of data between servers and other web applications. Working on the back end server side, they write code in relevant programming languages within the node.js open run platform.
The work of Node.js developers is centered around writing and developing code for the server side so that the integrations and requests with other applications are responsive and performed efficiently. This enables the growth and development of websites and applications in line with the business and its needs.
When recruiting Node.js developers, you need to be sure that the candidates you hire have what it takes to carry out the role effectively. This article delves deeper into what these skills and abilities are, along with ways you can evaluate candidates to ensure you hire the best people for the roles you have to fill.
What should Node.js be able to do?
Many businesses in various sectors use Node.js to build and develop their website applications to meet client demands and enable business growth. The Node.js platform is primarily used to scale applications within a website and back-end API, adding features that run in real-time.
The main duties of a Node.js developer focus on integrating the server-side logic with the front-end components of an application as created by front-end developers.
They need to be able to work with different stakeholders in the business, understand requirements, design and develop schemes that depict what the company wants.
Taking these requirements, Node js developers then work on integrating various sources of data and relevant databases with the application and appropriate integrations resulting in scalability.
Node.js developers must work closely with front-end developers to ensure an application's back-end links to front-end technologies. They also need to understand the principles around how to scale an application, ensuring that the designs they create are feasible and will meet the specifications set out.
Skills to look for in a Node.js developer
Successful Node.js developers possess several skills that mean they can carry out their roles effectively. During the hiring process, assessing your applicant pool against these skills is advisable to ensure that you hire the most suitable candidates.
Reading comprehension: having the skill to read and understand specifications, requirements, or information provided by stakeholders ensures that Node.js developers understand what their client is looking for.
Active listening: Node.js developers work with many stakeholders in their roles. They must communicate effectively, actively listening to what clients are asking and asking relevant follow-up questions to elicit further information, especially when clients may not be IT literate.
Logical thinking: Node.js developer needs to use their analytical and logical thinking in their daily role. Designing systems and ensuring that any issues with integrating data sources or servers with the application's front end are resolved calls for effective problem solving and logical thinking.
Error checking: a large part of a Node.js developer's role is to write code. They need to pay attention to every detail, ensuring that it is error-free, spot any discrepancies, and resolve them where issues arise.
Node.js platform skills: a Node.js developer must have practical working knowledge of how to use the Node.js platform. They need to understand how the system's functionality works, the modules within it, and how these are used to create the required outputs.
Useful abilities for a Node.js developer
Successful Node.js developers share several inherent abilities. These abilities are essential if a Node.Js developer is to do well in the role and meet the demands of clients and stakeholders.
Deductive reasoning: The ability to problem solve using inductive reasoning is essential if a Node.js developer is efficient in their role. Understanding specific information, analyzing, and using this to form logical conclusions enables them to work productively with others.
Inductive reasoning: Node.js developers work with various sources of information. The ability to make sense of this information, make logical inferences, and then use it when solving problems ensures that they maximize the available data sources.
Numerical reasoning: understanding numerical data in various forms, applying mathematical principles to manipulate this data, and then using when problem-solving means that they can carry out their role effectively.
Visual awareness: The ability to visualize parts, shapes, or how something will look when it is rotated, transformed, or in a mirror image means that Node.js developers can design systems and integrations.
Written comprehension: understanding written information and interpreting it to extract the key messages helps Node.js developers meet the requirements of the people they are working with.
Which soft skills tests could I use to hire a Node.js developer?
When recruiting Node.js developers, several pre-employment screening tests can be used to ensure those you hire have the soft skills needed.
Accountability: taking ownership of their decisions and being able to explain these to their stakeholders is vital for all Node.js developers. This scenario-based assessment evaluates an individual's integrity and discipline in the role to see if the position matches their beliefs and attributes.
Teamwork: a scenario-based assessment that assesses whether candidates can work with others effectively to create a productive and harmonious work environment. The test also looks at whether individuals can deal with challenging situations when working in a team to achieve a shared objective.
Problem-solving: this assessment determines whether individuals can work under pressure to solve complex problems. The test is timed and scenario-based, evaluating whether candidates can demonstrate critical reasoning in the context of the problem to reach the best outcome from the options given.
Which technical or aptitude tests could I use to hire a Node.js developer?
The assessments that you can use to determine whether candidates in your applicant pool have the required technical skills and aptitudes are detailed below:
Logical reasoning: a timed assessment using non-verbal information such as shapes or diagrams. This tests a candidate's ability to solve complex problems using both their inductive and deductive reasoning skills.
Diagrammatic reasoning: a test that uses sequences or patterns to determine whether candidates demonstrate the ability to work with abstract information to solve problems. This test also assesses whether individuals can adapt to new information, work under pressure and make logical decisions.
Verbal reasoning: an assessment of a candidate's ability to read and understand text passages, then use what they have learned to make logical inferences. This test is a timed, multiple-choice assessment.
Error checking: a timed test that assesses an individual's attention to detail. Candidates must identify any errors in lists of information, and select which multiple choice answers are correct in completing the information or matching the data given.
Node.js developer test: all Node.js developers need to be able to have the ability to use the Node.js platform and its functionality. This test assesses an individual's understanding of the platform and how to utilize the platform's functionality within their role.
