Top 20 Software Engineering Interview Question of 2022

Q1. What is Software Engineering?

Software engineering refers to the systematic, disciplined and quantified approach that software developers use when developing, operating and maintaining software.

Q2. What is SDLC?

SDLC stands for Software Development Life Cycle. It is a sequence of steps for software development. It includes the following phases: Requirement Gathering, System Analysis, Design, Coding, Testing, Maintenance, and Documentation.

Q3. What are the various models available in SDLC?

There are several software development models that can help you complete your project, including the Waterfall model, V-Model, and Agile model.

Q4. Explain the term Baseline.

Baselines are project milestones that are set by the project manager. They can be used to evaluate how far the project has come and its overall status.

Q5. What is a framework?

A framework has been a well approach to software development and deployment. It is a collection of tools which enables the development of software by delivering instructions on how to make it on a high level instead of providing specific details. The Software Process Structure serves as the foundation for the software development life cycle as a whole. The traditional software configuration also includes the umbrella operations.

Q6. What is Cohesion?

The degree where the components of a subsystem are interconnected is referred to as cohesion. It functions as an internal glue that holds device features together. Cohesion is a key sign of successful software.

Q7. What is Coupling?

The degree of interdependence between modules is called coupling. Good software has low levels of coupling, meaning the modules are independent of each other.

Q8. What is the main difference between a computer program and computer software?

The primary distinction between software and a program is that software is a set with several applications used to accomplish assignments, whereas a program is a sequence of instructions represented in a computer program. A program can be software, but the reverse is not true.

Q9. What is Software Configuration Management?

The procedures of monitoring and influencing changes that happen during software development process is known as software configuration management. Any modification made as a result of software must be monitored using in the well and managed procedure.

Whatever modifications made during software design are managed through a well-defined procedure, thanks to configuration management.

Q10. What does a software project manager do?

The software product manager is a member of the product management department and provides guidance to their company’s product. They work across departments to provide the best possible interface for the user.

Q11. Define Quality Function Deployment (QFD)?

The Quality Function Deployment (QFD) method converts a requirements of the customers into a technical specification. It focuses on making the software engineering procedures as user-friendly as possible.

Q12. What is ERD?

The graphical representation of the object connection pairing is the entity relationship diagram. It’s most generally utilized in database applications.

Q13. What is DFD?

The data flow and modifications that are performed to the information as it flows from source to the destination are displayed in a data flow diagram.

Q14. What is Software Quality Assurance?

Software Quality Assurance is a collection of audits and documentation functions that evaluate the efficacy and accuracy of quality control processes.

Q15. What is COCOMO model?

Constructive Cost Model is a suitable for comparison that estimates the number of staff months needed to produce a software product.

Q16. What are Software Metrics?

Software metrics are quantitative measures of a program’s properties. Use software metrics for a variety of things, such as analyzing software performance, planning productivity, and more. Load testing, stress testing, average failure rate, code complexities, lines of code are all software metrics.There are several advantages to using software metrics, including the following:

  • It saves money.
  • It boosts the return on the investment (return on investment).
  • Workload is reduced.
  • Points out areas where you can improve.

Q17. What is Software Configuration Management?

There is always room for improvement, and changing or adding changes to an existing system should be examined before being implemented. Changes to the system should be recorded before being enacted, documented with details of before and after, and controlled in a way that improves quality and reduces error rates.

Software Configuration Management is a technique for systematically managing, organizing, and controlling changes in documents, codes and other entities. The goal of this process is to enhance production while avoiding making mistakes.

Q18. What is SRS?

SRS stands for a Software Requirement specification document. It is used to capture all functional and non-functional requirements of a product. Not all SDLC models follow SRS documents, some use user stories as a capturing tool, and others use excel sheets.

Q19. What is software quality software quality attributes?

Software Quality Attributes are characteristics that help Software Testing consultants monitor the effectiveness of a software application. These characteristics include availability, integration, accuracy and consistency, ease of understanding, robustness, manageability, concision, expandability, and reliability.

Q20. What is the purpose of ER diagram?

An entity relationship describes how certain entities are related to one another. It might be referred to as the blueprint that supports our business process management, as it provides a visual description of the links between various kinds of data.
