I got call from Deloitte on Monday, about the interview scheduled on Saturday and told a formal mail will be sent in couple of days. As said, I have received formal interview call letter a day before the interview. Reached by 10.15AM for the interview scheduled at 11AM and returned by 3PM. Round 1: Technical Round 1 Mostly logical and scenario based question. Overall I enjoyed as they didn't tested my memory instead my knowledge and understandings.
1. Scenario: A patient wants to schedule an appointment with a doctor on a particular time.
Eg: hospital-->department-->doctors-->patient
  • How the tables looks like and its relation?
  • How the class hierarchy will be and its relation?
2. Questions from Design patterns as I have mentioned it in my CV
  • Factory vs Abstract Factory
3. Spring Dependency Injection
  • Setter vs Constructor injection and which is better
4. Questions from Group by in oracle sql
5.  Program or logic to find the count of a pattern in a circular linked list
6. Questions from Java 8 new features
Round 2: Technical Round 2
  1. A brief intro about myself, project worked, and the technology I know
  2. Write java program to iterate and find unique words and its count
  3. Agile scrum model
  4. Questions from Spring Boot
I have been asked to wait... Round 3: HR Round I had confident that I will be selected as I have answered well, except Hibernate related as I'm not aware. Finally HR has told that I will get the feedback on Monday(which means I'm not selected) and then left the place. Better luck next time!! :(
