How to hire a JSON developer? Skills to look for, interview questions, and more

JSON (JavaScript Object Notation) is a common data format used for asynchronous browser–server communication, including as a replacement for XML in some AJAX-style systems. This open-standard file format applies the human-readable text to send data objects consisting of attribute-value pairs and array data types. Though the language-independent data format JSON was derived from JavaScript, many programming languages incorporate code to produce and parse JSON-format data. As JSON allows to store information in an organized and easy-to-access manner.

Due to various multi-tasking features the demand for hiring remote JSON developers is rising among companies worldwide but to hire a JSON developer is not as easy as it looks. If you don’t have the adequate technical knowledge to hire a JSON developer then this process can become more difficult for you.

So, to help you get an idea about how to hire JSON developers and what skills to look for, we’ve created a thorough guide. Check out the list of mentioned qualities and interview questions to properly vet applicants. Try to hire JSON developers with at least a few years of experience showcasing the capability of driving projects.

Skills to look for in a JSON developer?

At a high level, JSON developers should have the following skills in his/her arsenal:

1. Ablility to develop SPA consuming server-side JSON restful services

One of the primary skillsets to look for when you hire JSON developers is their expertise in developing SPA consuming server-side JSON restful services. Instead of building the UI traditionally, SPA designs require different coding. So, when you hire remote JSON developers, always look for professionals well-versed with modern web front-end development skills.

2. Understanding of data structures and algorithms

Every programmer should know several data structures and algorithms. Understanding of dynamic array, linked list, stack, queue, binary search, hash map, merge sort, etc. is essential for JSON developers. These help in deriving other algorithms and data structures as well.

3. Efficient in version control

Versioning JSON is adding new properties and never removing or renaming existing properties. Therefore, JSON developers need to be knowledgeable in different version control systems to track changes to files for retrieving specific versions later. So, when you hire JSON developers check their expertise in different VCS, specifically Git.

4. REST API & SQL Server

A JSON developer must have good working experience in JSON REST API and performing Data Analytics using the SQL Server. Further, knowledge of SSAS and SSRS is an added advantage as the developers often need to work on TFS customization and reporting using SSRS.

5. Expertise in DOM Manipulation

DOM or Document Object Model supplies the programming interface for a document on the web. It serves the structure and the content of any web document, including its styles and HTML segments. Many of the technologies used in front-end web development are built on the DOM manipulation principle. Hence, JSON developers with expertise in DOM are a good choice if your users aren’t one-size-fits-all. DOM manipulation allows the developers to create more personalized and responsive web experiences.

6. Ability to communicate

For any developer job, including remote JSON developers, communication skills are a must-have to be successful. Interpersonal skills are not just crucial for one’s career development but help organizations to fine-tune the development processes from time to time. Whenever looking to hire JSON developers, look for candidates who are confident enough to work with different teams and can communicate effectively.

Top 7 JSON developer interview questions

When looking to hire JSON developers, it is important to test their knowledge with the right set of questions. Here’s a list of interview questions you can utilize to hire developers.

Though this is a pretty basic question, the way the programmer answers can give an idea about his/her experience. The answer might be like - JSON, the abbreviation of JavaScript Object Notation, is one of the simplest data interchange formats, independent of programming language and platform. The lightweight text-based structure of JSON makes it easily simple and readable.

JSON is often applied for serialization and data transmission between the network connections, which makes it a popular alternative to the XML format.

JSON syntax is a set of JavaScript object notation syntax.

  • Data is in name/value pairs
  • Data is separated by a comma
  • Curly brackets hold objects
  • Square bracket holds arrays

Check if the developer mentions all major points that make JSON popular over XML.

  • JSON is faster and lighter than XML
  • JSON objects are typed, unlike the typeless XML data
  • While JSON types are number, array, boolean, and string. XML data are all string
  • While XML data needs to be parsed and allocated to the variables using APIs, JSON is easily accessible through JavaScript programming.

Almost all the new versions of the browsers like Internet Explorer, Chrome, Safari, Mozilla Firefox, etc., support JSON format.

Though there are multiple libraries available for JSON in .NET, the most popular ones are -
Newtonsoft - the most widely used framework that converts using c#, and is well-known for its flexibility and performance
DataContractJsonSerializer - a built-in library provided by Microsoft handles JSON objects within the .NET environment

JSONP is the same as JSON with padding. This method is useful for circumventing the cross-domain policies in web browsers. JSONP is the easier way to deal with browser restrictions when transmitting JSON responses from various domains to the clients.

JSON is a simple data format applied as a communication medium between different systems
On the other hand, JSONP is a methodology for applying JSON format with cross-domain ajax requests without being influenced by the same-origin policy concern
