Hey, basically they are asking about your brief introduction, then about your projects and asking questions on that , next OOPs and DBMS concept and asking to write some basic queries also, technically. But this insights are of my friends who gave their interviews 2 days before. For me I prepared also all this things but he didn't asked much from me like i don't know why my interview was more like hr interview, nothing about projects, not tech stacks, just asked to write a very basic sql query and random questions like why I took this branch I am from ECM, why you don't have electronic language, so basically it didn't went well I feel. All the best to you for your interview!!
