For starters,
you should learn the differences between quality assurance and software testing, in my opinion.
If you told me that QA and testing were the same, then I most likely would quickly end the interview and say goodbye.
You should also have a good understand of what "quality" means in terms of software applications and organizations that use
software applications. What does it mean to "assure quality"? Does "quality" mean "it works" or is there more?
Good luck!
