24. What is the difference between Quality Assurance and Quality Control in software testing?
How to Answer
This question is a hybrid between both a technical question and an operational question. The interviewer is seeking to understand your knowledge of the quality function in the software development process and also how you use quality measures when developing an application. Make sure you address both of these concerns in your answer.

1st Answer Example
"Quality Assurance or QA is a planned, systematic way to ensure quality throughout the application development process. It is a component of the process which tests the outcomes and adjusts the process to reduce errors. Quality Control or QC is the final testing of the application to discover any faults or bugs in the software. QC uses the process developed by QA."

2nd Answer Example
"Quality Assurance, or QA and Quality Control, also known as QC, are both processes whose goals are to eliminate defects in a software application. The difference is that QA is performed throughout the development process and identifies steps in the process which are responsible for the errors the QA testing has identified. These steps are then modified to eliminate future errors. QC is performed at the end of the development process to ensure the application functions properly. QC follows guidelines developed by QA."
