15 commonly asked software developer interview questions
Software developers are among the most sought-after and highest-paid professionals in the IT industry. This is because software development is an integral part of most businesses and organizations, and a successful software developer can make a huge difference in how a business operates. A Bachelor of Computer Applications (BCA) is a great way to get the skills and knowledge you need to become a successful software developer. Nowadays. Online BCA courses are open for enrollment that allow you to study at your own pace.
An experienced software developer with 10–20 years of experience makes an average pay of ₹15.5 Lakhs per year, compared to mid-career software developers with 4–9 years of experience who make ₹8 Lakhs a year. So, it’s obvious why there’s demand for software development-related courses and jobs.
How BCA prepares you to become a software developer?
BCA is a three-year undergraduate program that provides students with a comprehensive understanding of the basics of computer applications. The program covers a range of topics, including programming languages, databases, operating systems, networks, and software engineering.
The curriculum also includes software engineering and project management, which are key skills for software developers. Students learn the principles and concepts of software engineering, such as software design, coding, testing, and debugging. They also learn project management skills, such as planning, scheduling, and monitoring projects.
Software developer interview questions and how to answer them
When interviewing for a software development role, it’s important to be prepared for the questions that could be asked. Here are some of the most commonly asked software developer or software engineering interview questions and how to answer them:
Q. Why did you choose to become a software developer?
A. I became a software developer because I am passionate about technology and creating innovative solutions to solve problems. I enjoy the challenge of developing software and the satisfaction of seeing the result.
Q. What did you choose as your software development project and why?
A. My software development project was a web-based application that provided users with a streamlined way to manage their finances. I chose this project because I wanted to create an application that would help people better manage their money and make financial decisions.
Q. What kind of technologies have you previously worked with?
Q. What are the programming languages you are familiar with?
Q. Key differences between functional and object-oriented programming?
A. The key difference between functional and object-oriented programming is that functional programming focuses on the evaluation of functions, while object-oriented programming focuses on creating objects that contain data and methods.
Q. What are the key aspects of a code review?
A. The key aspects of a code review involve assessing the code to ensure that it is efficient, well-structured, and correctly documented; that it adheres to coding standards and best practices; that it is free from errors; and that it is optimized for performance. Additionally, a code review should also check for security vulnerabilities, code compatibility, and maintainability. A code review aims to identify and address any issues with the code before it is deployed, ensuring that it meets the necessary quality standards and is fit for purpose.
Q. Have you been a part of the agile software development process?
A. Yes, I have been a part of the agile software development process. I have experience working in an Agile environment, and I am familiar with the various processes and tools used in Agile development, such as Scrum and Kanban.
Q. Tell us about responsive design.
Q. How do you find and test bugs in an application?
A. To find and test bugs in an application, I use a variety of techniques, such as unit testing, integration testing, and regression testing. I also use debugging tools, such as breakpoints and logging, to identify and fix any bugs that may be present in the code.
Q. Differentiate between blocking and non-blocking calls.
A. Blocking calls are calls that pause the execution of the program until the call finishes. Non-blocking calls are calls that do not pause the execution of the program and instead return immediately, allowing other tasks to be performed at the same time.
Q. What do you know about white box and black box testing?
A. White box testing is a form of software testing that looks at the internal structure of an application, such as the source code, control flow, and internal program structure. It is also known as clear box, open box, logic-driven, code-based, or glass box testing. It is used to examine the path of execution within an application to ensure that all functions perform as intended. This type of testing is often used to look for security vulnerabilities, bugs, or any other type of coding issues that could affect the application’s performance.
Q. List the differences between functional and non-functional requirements.
A. Functional requirements are those requirements that specify what a system should do, while non-functional requirements are those that specify how the system should perform. Functional requirements focus on the features of the system, while non-functional requirements focus on the performance, security, and reliability of the system.
Q. What is refactoring?
A. Refactoring is the process of improving the structure and readability of code without changing its behavior. This is done by restructuring existing code, eliminating code duplication, and using simpler and more efficient algorithms.
Q. Tell us about the debugging tools you know.
A. I am familiar with a variety of debugging tools, such as breakpoints, logging, and profiling, which can be extremely helpful in identifying and troubleshooting issues within code. Additionally, I often use unit testing to verify that the code is functioning as expected and to identify any bugs that may be present. This is a great way to ensure that the code is bug-free and that any existing issues are quickly resolved. Ultimately, debugging tools are an essential part of the development process, and I have a lot of experience with them.
Q. What do you know about distributed systems technologies
A. I am well-versed in multiple distributed systems technologies, such as message queues, distributed databases, and microservices. I have a deep understanding of distributed computing fundamentals, and I am experienced in building and maintaining distributed systems. Additionally, I am knowledgeable about the various tools and approaches that are used to build, deploy, and manage distributed systems.
These software development interview questions are invaluable when preparing for an upcoming software development interview. They will allow you to better understand the topics you should be prepared to discuss and what kinds of questions to expect. With these questions, you can gather the knowledge necessary to ace your software engineering interview questions and make a great impression on your potential employer.
