I applied for the senior java developer role. During interview they will make sure that you are fit candidate for them. So interview duration is high 90 minutes. As you join the interview an online IDE link will be shared where interviewer will ask you to code, and run to show desired output along with the theory knowledge check. 
First question will be tell me about yourself and you can expect 5-6 questions on your previous project technology how you implemented things.Then he will start asking basic questions on java and write program for them based on String, making class immutable. Counter questions will be there why we write like this only if we will use this what will happen. So basic good conceptual knowledge is must. Then the level will increase he will ask question from each topic Collections, multithreading, Exception Handling and also let you to write code based on some conditions and counter questions will be there.
If you have knowledge of java-8 features then to check complete understanding he will ask to write program using lambda expression, streams, concurrency in java and producers, consumers, function, garbage collection. Questions on memory management and what all features added in java-8 will be there. For spring boot annotations will be asked what is the use of which annotation.
