Software Developer Interview Questions

A software developer is a specialist tasked with creating software for both commercial and consumer use. They closely collaborate with clients to ascertain their needs before using computer languages like Java or C++ to develop programmes. Here are the top 10 interview questions asked during the technical interview to a software developer candidate. 

1. What are the different categories of software?

Software products can be broadly divided into: 

  • System Software: Operating systems, compilers, drivers, and other types are included in this category. 
  • Software for networking and web development: Networking software gives computers the ability to communicate with one another and with data storage facilities. 
  • Software that is embedded within devices including washing machines, satellites, microwaves, TVs, and other instrumentation and control equipment 
  • Expert systems, decision support systems, pattern recognition software, artificial neural networks, and other software types fall under the area of artificial intelligence. 
  • Software for scientists and engineers that supports their needs in carrying out enterprise-specific tasks AutoCAD, for instance, and MATLAB are examples.

2. What are the characteristics of software?

The following six factors define software: 

  • Functionality: The capabilities of software are referred to as their capabilities. A calculator, for instance, can be used to execute mathematical operations. 
  • Efficiency: It is the capacity of the software to make the best use of the resources made available to it. Software that is more efficient uses resources more effectively and costs less. 
  • Reliability: The likelihood that software will run without interruption in a given setting. It is an essential quality of software. 
  • Usability: This term describes how well a user can use a piece of software. The level of user happiness is influenced by usability.
  • Maintainability: It is defined as the simplicity with which software code may be fixed, enhanced, and understood. Software maintenance is a stage in the software development cycle that starts after the customer receives the product.
  • Portability: The term “portability” describes how easily a software product may be moved from one environment to another.

In addition to the qualities listed above, the software has the following qualities:

  • Software is engineered; unlike hardware, it is not created or produced. The process of making hardware includes development. Software does not involve any manufacturing.
  • The software is impervious to aging.

3. What is verification and validation?

The phrase “verification” refers to a group of procedures that guarantee that software carries out a particular purpose.

Validation describes a group of procedures used to make sure that software created to meet client needs is functioning properly.

4. What are the various steps involved in the software development process?

The steps involved in the software development process are:

  • Requirement analysis
  • Specification
  • Software architecture
  • Implementation
  • Testing
  • Documentation
  • Training and support
  • Maintenance

5. What language do you like to write programming algorithms in?

Every developer has their own opinions about the available programming languages. However, because they are dynamic, high-level languages should be preferred. Languages like C and C++ are popular examples. 

6. What is computer software?

Computer software is a package that comprises a programme, related documentation, and an instruction manual.

7. What is a framework?

A well-known technique for creating and deploying software is the use of frameworks. It is a collection of tools that enables the creation of software by offering abstract instructions as opposed to precise instructions on how to do it. The foundation of the entire software development process is the software process framework. The software process structure also contains the umbrella activities.

8. Name the different SDLC models in use.

  • Waterfall model
  • Spiral model
  • Incremental model
  • Agile Model
  • Big bang model
  • Iterative model

9. Which is considered the best SDLC model?

Agile is the greatest SDLC methodology and one of the most popular SDLCs in the IT industry, according to the annual State of Agile study. It works effectively in a flexible setting since it is a hybrid of incremental and iterative approaches. Therefore, choose the type that best meets your needs.

10. What is meant by debugging?

In the context of software engineering, debugging is the process of locating a software bug. In other words, it refers to the process of identifying, analyzing, and fixing issues. When software fails to function as intended, debugging becomes crucial.
