* Brief introduction * Java Stream API question * How do we create a final class * Two Objects added in set. Will they be equal? * 1 example of deadlock and how it could be prevented. * What annotations you have used. @Transactional usage. * Asynchronous programming in Java. Whiteboard session- 1 would be basic questions (in my case sum of fibonacci series). If you succeed this then a more difficult problem which you are not expected to solve completely but your approach would be checked.
