23. What are Verification and Validation, and how do they differ?
How to Answer
Another hybrid question, which addresses both technical and operational competencies. Again, the best approach is to define the terms, discuss how each process is used in application development, and, if necessary, provide an example. Like most technical questions, your answer should be direct, succinct, and brief. Let the interviewer ask a follow-up question if they need additional details or want to explore the topic in more depth.

1st Answer Example
"Verification is a static testing process while Validation is a dynamic test. Verification evaluates each step in the process to ensure it meets the requirements for that stage of the process. Validation occurs at the end of the development process to confirm that the software meets its specifications and performance metrics. Verification focuses on the process, while validation focuses on the product."

2nd Answer Example
"Verification and Validation are both testing procedures, but they are different from each other in several ways. Verification is process-focused and looks to confirm that each step in an application development project meets its requirements. Verification looks at documents, requirements, and specifications and uses checklists. Validation is product-focused. Its purpose is to examine the final product to ensure it meets the specifications of the user. Validation uses dynamic testing methodologies while verification is a static process."
