Just like all squares are rectangles but not all rectangles are squares, similarly all tasks are activities but not all activities are tasks.

In BPMN terminology, activities represent work completed by a group or organization. A process, sub-process, or task are all types of activities.  Some activities are atomic (a task) while others are not atomic (process and sub-process) since they can be further decomposed.

So you can use the generic term activity when discussing processes and work being done.  But if you want to be less ambiguous in your meaning the terms process, sub-process, and task should be used.

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.
