Introduction to QC Interview Questions and Answers

Organizations follow a set of procedures known as Quality Control (QC) to ensure the efficient delivery of high-quality products that meet customer demands and satisfaction. International standards serve as a reference for these procedures, which guarantee the quality output of software systems or products. Different parameters that will be considered for Software Quality are functional requirements and non-functional requirements, which directly and indirectly affect the product, such as performance, usability, and supportability. During the product’s performance, handling unexpected scenarios or situations and evaluating error rates are key considerations.

Software Quality Assurance is different from Software Quality Control as software quality assurance encompasses the various standards and processes for the stable maintenance of the quality of the products, e.g., software deliverables, processes, and documentation, reducing the number of defects, etc. In contrast, software quality control is a kind of artifact compliance validation against the established requirement criteria in finding the defects.

If you are looking for a job related to Quality Control, you must prepare for the 2023 Quality Control Interview Questions. Every interview is indeed different as per the various job profiles. Here, we have prepared the critical Quality Control Interview Questions and Answers to help you succeed in your interview.

In this 2023 Quality Control Interview Questions article, we shall present the ten most important and frequently asked Quality Control Interview questions. We can divide these questions into two parts as follows:

Part 1 – Quality Control Interview Questions (Basic)

This first part covers basic Interview Questions and Answers.

Q1. What is Software Quality Control and explain its benefits?

Answer:
Software Quality Control comprises a set of standard procedures followed by organizations, institutes, or international groups based on reference standards. These procedures aim to ensure the delivery of efficient and high-quality products that meet customer satisfaction and requirements. The several benefits of Software Quality Control are as below –

It is possible to increase the efficiency of the software system or product.
Product defects can be minimized before delivery.
It is possible to reduce the development time.
It is possible to improve the customer satisfaction index.
Establishing strong trust and relationships with the client is possible.
Faster application development with a smaller number of defects.

Q2. What are the different steps or processes involved in the Quality Control Procedure?

Answer:
This is the basic Quality Control Interview Question asked in an interview. The Quality Control Procedure involves several steps or processes, including reviewing and testing the product according to the requirements. The steps involved in the Review and Testing phases are mentioned below–

Reviewing Phase:

Requirement Analysis
Design Phase
Code Build and Development
Application or Code Deployment
Test Plan phase
Implementing test cases

Testing Phase:

Unit Testing
Integration Testing
System Testing
System Integration Testing
Non-Functional Testing
User Acceptance Testing

Q3. What are the different types of Quality Control Parameters available in Software QC?

Answer:
The different types of Quality Control Parameters available in Software Quality Control are Products, processes, and Resources, which are explained below:

Products: The products refer to the customer’s actual requirements, which need to be delivered without any defects.
Processes: The processes define the rules or procedures that should be followed during the testing of the software system or product, ensuring the delivery of the best product. The set of processes will enable the testing procedure to be carried out efficiently to test the complete product without missing any functional or non-functional inabilities per the customer’s required specifications.
Resources: Resources to be deployed are to be very efficient in terms of team or tools or technologies used. Depending on the project’s budget, one can execute the testing procedure automatically or manually. If manual, efficient resources should be available within the team to avoid any manual errors or defects. In contrast, Automated testing also needs a technical professional to be deployed.

Q4. What are the different types of Quality Control Processes involved?

Answer:
The different types of Quality Control Processes involved are Plan, Do, Check, and Act, and they are explained below –

Plan – In this stage, we follow and consolidate all Quality Control processes into a single test coverage document or a Test Plan Document.
Do – This stage defines all the Quality Control processes as parameters to develop the Quality Standards.
Check– This is a stage where all the Quality Control processing parameters meet the quality as per the prescribed standards.
Act– This stage involves taking necessary actions to ensure quality, repeating them if necessary, and implementing corrective actions.

Q5. What types of testing are performed as part of Quality Control processes?

Answer:
The different types of testing performed as part of Quality Control processes are such as Unit testing, Functional testing, Integration testing, System Testing, System Integration Testing, Non-Functional Testing, User Acceptance Testing, Beta Testing, Performance testing, Regression testing, Volume testing, Recovery testing, Usability testing, Stress testing, Load testing, and Installation testing.
