My interviewer asked how you know data is updated or saved or deleted in datatbase in hibernate session?

There are only two case: query will execute successfully or will throw an exception. Use exception handling and you will easily know the result.
If not satisfied, every query execution(saving or updation) return a acknodgement. saving return the generated primary key and updation or deletion return the number of records that has been updated. If the transaction fail due to an exception. You could easily know that the query executed successfully with the help of that acknoledgement
