Business Analyst Interview Questions

Hi, thanks in advance for your responses. I am applying for a business analyst role at a finance company whose main product is a "platform" that is used by financial professionals. I have an interview coming up and to be honest, I am not sure what to expect from the interview because it seems a business analyst's description is not consistent from job post to job post. I am assuming it's more in line with what a systems analyst would be doing i.e. designing documents, doing some quality assurance tasks, etc. My question is, what sort of things can I expect to be prepared for for this type of interview? Obviously anything is fair game, but what are some common things that I can expect? I appreciate your feedback. Thanks.
