We are looking for an enthusiastic junior software developer to join our experienced software design team. You will report directly to the development manager and assist with all functions of software coding and design. Your primary focus will be to learn the codebase, gather user data, and respond to requests from senior developers.
To ensure success as a junior software developer, you should have a good working knowledge of basic programming languages, the ability to learn new technology quickly, and the ability to work in a team environment. Ultimately, a top-class Junior Software Developer provides valuable support to the design team while continually improving their coding and design skills.
In this guide, you will find some of the most popular interview questions and answers on Node.JS that you can ask your potential employees. We will cover basic questions regarding JavaScript or Node itself, as well as complex questions about internal development, and help you to prepare for the interview!
To be consistent, we will start the article with an overview of the basic questions and answers to Node.JS interviews that you can ask junior developers. These questions can be asked at the beginning of the interview, after the candidate introduced themselves and spoke a little about themselves.
First of all, this is a really good tactic to get to know the developer as a person. The way they answer questions, where they stop and start thinking, and other small details like this, can actually say a lot about the developer, especially about the amount of work they actually put into studying the subject.
Another reason why these basic Node.JS interview questions are so important is because you can check the basic level of Node.JS knowledge. After you evaluate the level of qualification of the candidate, you can decide what type of difficult questions you should give the developers later.
One of the more subjective interview questions about Node JS. The candidate should express their opinion about the tool and its benefits. Since there are quite a few of them, most likely the candidate will describe those that interest them or bring them the greatest benefit.
This is one of those Node.JS questions that may catch the developer by surprise, as it is not directly related to Node JS. This question should be one of the easiest for developers. It all comes down to how they would formulate the answer.
Junior developers are responsible for writing basic code, maintaining apps, addressing and resolving bugs, and distributing app updates. To accomplish these duties, junior developers collaborate closely with other developers.
Though it may appear that we are emphasising the importance of the interview, it is not that complicated, and there is no reason to be wary of it. However, anxiousness is natural, so here are some sample questions to help you prepare for interviews.
The reason behind asking general questions is for the interviewers to get to know you better. Whether you are responsible or good at communication is determined based on these questions. For example:
Code Institute has been training new software developers since 2015, and their career change is priority number one. Our careers hub and team are in place to help our new developers through the interview process and much more. The careers team is why 98% of career services users are employed within a year of graduation.
