First, you should prepare yourself with basic knowledge of scrum. Then, get the sample questions, books and video courses like Mindcypress's courses on scrum. Once you have complete basics and sample questions, then you will be able to know what kind of questions you should expect and how to prepare for that. Most of the questions are situational. It is not necessary that questions are asked in the same way. It can be a little different. That is why sample questions are helpful. You will get an idea of what each question is expecting from you.
