Interview will be average. They will ask you basic android question. As the company works on Kotlin so they will ask questions related to kotlin as well. If you clear your first round then you will be assigned a simple task which you need to finish in 3-4 days. Third round will be where they will be asking logic and idea about the assignment you submitted and in the same there will be managerial round to check whether you are good fit for the company or not.
