Software development is a very technical field. As such, you need job candidates with the right skills and knowledge about the latest tools and technologies.
To achieve this, you need to ask fundamental interview questions that reveal your applicants’ technical and soft skills.
2. What is the difference between undeclared and undefined variables?
This one is another fundamental question for JS developers. Regardless of work experience, these developers should be familiar with both terms. Knowing the difference between the two is important to help troubleshoot scripting errors.
As its name suggests, a callback function is a function that is called after another function was executed. The function is then called back after completing an operation after being passed to another function as an argument.
All great developers have the drive to learn and improve constantly. With questions like this, you can learn how passionate the candidate is about keeping up to date in his or her field of expertise.
It would help if you took note of their answers. This way, if you move forward in hiring, you’ll already know how they prefer to improve their skills and stay knowledgeable. You can supplement their way of learning once they are on board with your team.
5. How do you handle receiving feedback? How does feedback impact your choices as a developer?
This open-ended question aims to check whether a candidate can follow instructions and accept feedback. Note what you like and dislike about their answers and try to understand where they’re coming from.
6. How do you implement automated testing in your JS code?
Web application testing is essential when building robust code. The best and most experienced developers understand the importance of automated testing and have the know-how to implement them.
Automated testing is essential to produce a bug-free program. There are three ways to do them:
- Unit testing
- Functional testing
- Integration testing
I usually use tools for automated testing, including Jest, Karma, Mocha, Cucumber, Casper, etc.
7. Which JS frameworks do you have the most experience with? Why do you prefer these over other popular frameworks?
There are always tradeoffs in software development using any web technology or programming language. Developers who are aware of these disadvantages are more likely to have a deeper understanding of the tools and technologies they are using.
9. How do you resolve conflict with other team members?
In a software development team, conflicts are common. In fact, a team that produces many ideas, sometimes causing some conflict too, is a sign of a healthy team. Thus, every member must know how to communicate their ideas well to reduce and resolve potential conflicts.
There are many communities in web development. Developers eager to learn and passionate about their craft are often active in one or more groups.
