Well the interview has three rounds 1) mcq round 2) coding/technical 3) hr round For the mcq well it could change but practice for it from chatgpt, geeksforgeeks, etc and it's related to core java so prepare it don't miss the datatypes size and brush up on all core java because if you know java then mcq is not hard. For the coding round also they will ask to code a program if you are good in coding and they will ask programs such as find the missing no from an array, method overloading, overriding, strings and other concepts so prepare well.
