Someone from HR would have contacted you for a chat if you are shortlisted. That person would ask you broadly your past experience. Depending on what you answer and the specialisation under digital business analyst track the person thinks you are suitable for and your preference, there will be a second interview. The second interview will be with the experts of that specialisation. You might also be asked to sit for an online test.
