When going for an interview after applying for a business analyst job you will be required to answer a couple of common business analyst interview questions. One of those business analyst interview questions might be to explain what is meant by logical data model. Your should answer shortly and quickly by explaining that a data motel is capable of telling and showing details about specific data that is physically stored in a database. Another interview question might have you explaining what a high level or low level use case diagram is. A high level use case diagram is a broad view of any business process. By dividing a high level use case into several sub use cases then we get what is referred to as a low level use care.
Another common business analyst interview question is what you know about SDD. This question should be answered very simply by saying that SDD stands for system design document and it is just a middle step dividing business users and developers. It allows developers to understand the business requirements. You may be asked how you make use case diagrams. You should reply by saying that you make use case diagrams by using MS Visio and Rational Rose.
