Black Box Testing is a form of software testing that focuses solely on WHAT the system should do and not HOW the software should internally accomplish it. No specific knowledge is needed of programming or the internal structures of the code.  The tester is only aware of what behavior or output should result from a given set of inputs.  
Black box testing is one of the most common types of testing in which a business or systems analyst will participate. Test cases are developed from the software specification of requirements.  The test cases will state that for a given set of inputs a specific set of outputs should be returned or that a specific outcome should occur.
Black box testing can be used to test for functional and non-functional system requirements, though the majority of black box testing focuses on functional requirements.
Black box testing is used during Unit, Integration, System, and Acceptance testing.

Do your homework prior to the business analysis interview!

Having an idea of the type of questions you might be asked during a business analyst interview will not only give you confidence but it will also help you to formulate your thoughts and to be better prepared to answer the interview questions you might get during the interview for a business analyst position.  Of course, just memorizing a list of business analyst interview questions will not make you a great business analyst but it might just help you get that next job.
