What are some of the QA processes you are familiar with and have worked with in the past?

While a Microsoft software developer may not be directly involved with the testing and quality assurance of the code they develop, who should be familiar with the processes. This will help them code for the requirements of the organization. The Microsoft interviewer uses this operational question to determine the quality control systems you have worked with and confirm that your processes are similar to the ones they use. Even if your experience isn't an exact match to theirs, you should be able to describe how you would quickly transition to their processes.
