Try booking yourself a set of movie tickets or shopping from an e-commerce app. Even simpler, enter something on the browser. Are you wondering how the content is continually changing and updating with real-time data or amazed at how you’re getting suggestions without typing all the details? It seems like magic doesn’t it? All this is a part of a detailed behind-the-scenes process commonly known as ‘Back-end Development.’ The back-end is all about maintaining a strong online presence while keeping the audience engaged with a unique set of technologies and languages. It powers the product’s growth, making the entire process of online browsing seamless.
Back-end web development is the backbone of software development. It is the process of writing codes that communicates with the front-end and shares relevant information to be displayed on the screen. The interaction happens through a series of requests sent to the back-end servers that store millions of terabytes of data, to help dynamic software maintain their elective presence and keep users interactively engaged. Back-end development also ensures that the software doesn’t crash often or have 404 errors that restrict the overall performance of the page. Now, all this is not powered by AI yet; it is done manually. It is thereby creating a high demand for proficient and experienced back-end developers.
A back-end developer is responsible for creating, maintaining, testing, and debugging the entire back-end. This requires a massive investment of time, patience and knowledge to master the art of just one language. One language alone is so exhaustingly comprehensive that the back-end engineer must be deeply involved in knowing its entire architecture. Additionally, back-end languages continually modify with upgrades and updates. In such a scenario, back-end developers can’t or rather shouldn’t afford to move to new languages and be a jack of all trades. This would reflect on their knowledge and skills.
The back-end is a critical component of both your website and the company’s success. Hence, in a digitally evolving world, your decisions can no longer be based on resumes and instincts. Your approach to finding an ideal back-end candidate is backed by a clear understanding of the skills and expertise relevant to both the tech stack and your business.
To help you take a closer look at the necessary skills set that summarizes the role of an ideal back-end software engineer, we’ve divided your hiring process into two parts.
Concerning the above diagram, these are the skills required by an ideal back-end developer:
While several technologies contribute to making ideal back-end developers, it is important to recognize the key languages and frameworks that set them apart. Understand their experience and exposure to different technologies to get an accurate picture of your back-end developers’ profile. At the same time, his skill set also has to be relevant to your project and your organizational needs.
One of the most celebrated software programming languages of all time that is used in more than 3 billion devices.
A powerful programming language designed with easy understanding for both beginners and seasoned developers.
Google’s latest development environment and programming language are efficient in developing and optimizing apps.
With a robust technology stack, Node JS is a universal language for both clients as well as server-side programming. Its unique runtime environment helps build fast, scalable network applications.
Ruby is a dynamic and elegant language that is extremely popular among developers owing to its blazing speed in creating new projects with high performance. Since 2002, Ruby has had 1,082 releases.
This may seem mundane, but the career of a back-end developer progresses within the same technology. They usually upgrade from basic concepts to design patterns to architecture if seeking advancements. It is rare and rather unadvisable for a back-end developer to change technologies and languages with time. However, they do have a close alternative. Depending on their expertise and learning agility, one can take up the challenge and venture into becoming a full-stack developer. Such developers work on both front-end and back-end with a working knowledge of various other areas like Databases, Version Control System, Designing, etc.
For example, becoming a MEAN STACK Developer requires proficiency in M- Mongo Database, E- Express JS, A- Angular JS, and- Node JS.
Another popular choice is LAMP STACK, wherein the foundation is L-Linux, A- Apache, M- MySQL, and P- PHP.
The types and skills of back-end developers vary greatly. Their skill sets vary from low-level algorithm design to higher-level database work. Hence, one of the best ways to evaluate a back-end engineer’s skills is by conducting a hands-on programming assessment. A specialized back-end developer test comprises a variety of coding tests that help solve hiring bottlenecks efficiently. They are available in diverse question types, including MCQs, case study simulators, coding simulators, etc. With data-driven evaluation methodology, intuitive user-interface and customized reports, recruit the best back-end developer through campus drives or resumes, within stipulated timelines.
The quality and coverage of our technical questions are unmatched as we cover a vast array of roles and skills. A rich repository of 100,000+ Technical Questions for 300+ Skills helps test a coder’s competency at every level comprehensively. You can choose from a set of readily-available standardized tests such as core Java test, Performance testing and load runner, python developer test, Java MySQL developer assessment, Security Assessment Testing, to name a few from our vast library of Programming Assessments. With a ready-to-use pre-build test set, assessing a coder’s skill instantaneously helps save precious time.
In case you are looking for something specific, we get our team of experts to build a customized assessment that you can’t find anywhere. These tailor-made pre-hiring assessments are an ideal filtration process to explore candidates’ desired skill sets without bias, not only for IQ skills but for coding skills as well. Tailored solutions matching organizational objectives with features and applications are offered at every level to assist you in hiring an ideal back-end developer.
