AMS Accountant interview questions

Interview process was fast, lasted a week. Typical screen call, then vitrual interview with manager and senior manager. Typical behavioral questions during screen call. At the virtual interview, was told that the role I applied has been changed to senior finance analyst. During the interview I was asked on skill questions on topics I have little or no knowledge of. I wish they could inform me about the role change prior to the interview. rather Wasted my time prepping and made myself sound like a fool.
