One of the lucrative fields and one with many prospects is SDLC. This essay is specifically for you if you’re thinking about working in this sector. In order to assist you ace the interview, we’ve put up a list of the top 7 SDLC interview questions.

Question 1: What is the Software Development Life Cycle?

A Software Development Life Cycle (SDLC) is a well-defined process for creating high-quality, low cost software as quickly as possible. The goal is to develop great software that exceeds all requirements and expectations from customers.

Question 2: What are the phases in the Software Development Life Cycle? 

Planning Phase: 

Understanding the client’s requirements is the first phase. This analysis is crucial since it aids the team in estimating the program’s overall cost.

Study Analysis:

Finding the precise goal and requirements of the Application is the second step of the software development life cycle. The development team takes into account these requirements when taking into account the code and structure of the product.

Design Phase:

The team will carefully design algorithms to implement the program code once the analysis and designing decisions have been made. The team writes the real code at one of the time-consuming stages.

Development Stage:

The team will carefully design algorithms to implement the program code once the analysis and designing decisions have been made. The team writes the real code at one of the time-consuming stages.


The team conducts testing to ensure that the code complies with the specified product requirements before proceeding to the final step. The program is examined using a variety of manual (penetration) testing and automation testing techniques. When the program is fault-free and capable of upholding quality standards, testing is declared complete. They must again develop fresh, accurate software if the test reveals an inaccuracy.


The product must now be delivered to its final users so they can begin using it. The majority of businesses like to roll out their product to 10–20% of users in the initial stage so they may detect any issues or vulnerabilities and fix them.

Product Maintenance:

 The SDLC doesn’t end here. Based on the client reviews, the team has to timely respond to any flaws & update them based on user feedback. The team commonly has to check the following activities at this phase:

  • Bug fixing
  • Continuous Monitoring
  • Timely upgrading apps to a new version
  • New and interactive add-on features
  • New & Interactive UI

Product functionality is also highlighted in this report in order to meet the needs of the stakeholders.

Question 5: Define Capability Maturity Model (CMM)

The capability maturity model is a criterion that assists organizations to lay a successful foundation to improve the process of software development. This methodology is implemented to enhance the quality of SDLC Testing and deliver the best to the end users.

Question 6: What are some of the best SDLC Tools

  • Jira – This software is created to identify errors and tasks that has evolved into a powerful workflow management solution.
  • Git – This is a customizable open-source software. It helps developers to easily evaluate the changes & contributions made into the code.
  • Confluence – This is one of the most astounding tools that assist in development of product research and easily share design assets.
  • Asana – Asana is a simple & flexible tool that helps you plan, organize the project so that the team works faster with more confidence & achieve their goals.

Question 7: What is the difference between quality control and quality assurance 

  • The dedicated support team’s responsibility for quality control is to make sure that correct product quality is upheld throughout the entire process of software engineering.
  • To ensure that the product is delivered to end customers with fewer errors and defects, the project’s testing team is in charge of quality assurance.
