But I'm from python background
The interviewer was from java background so that's why he told me this role is for java developer only
There will be two technical interview rounds, with the first one primarily focused on assessing my expertise in core Java concepts, including object-oriented programming, collections, multithreading, and exception handling, while the second round will dive more into the full-stack side, covering my experience with backend frameworks like Spring Boot, frontend technologies such as React or Angular, database integration, API development, and overall system design capabilities.
