Accolite Digital Interview Experience for Senior Java Developer
I received the Technical recruiter’s direct call for the role of Senior Java Developer – Backend. After initial discussion over the phone call. They scheduled the interview on Turbohire. There were 3 rounds:
- Technical – Video Interview
- Managerial – Video Interview
- HR – Telephonic discussion
First-round: Technical interviews: I was asked basic java questions:
- Java 8 Features
- Why needed a functional interface in java 8 if we can have a single abstract method in the interface or abstract class?
- Can we override default methods?
- Can we override static methods, if we do what will happen and output the program?
Java
class Base{ public static void hello(){ System.out.print( "Base::Hello" ); } } class Child extends Base{ public static void hello(){ System.out.print( "Child::Hello" ); } } class Main{ public static void main(String[] args){ //what would be output? Base b = new Child(); b.hello(); } } |
- Write a lambda expression to add two integers?
- Find duplicate words in a sentence. Similar to this: https://www.w3wiki.net/java-program-to-find-duplicate-words-in-a-regular-expression/
- Remove repeating characters from the string
Managerial Round: This round was mostly focused on the Project and Some questions on Spring boot and microservices.
- What is Dependency Injection?
- Bean scopes – Singleton vs Prototype
- @Transactional annotation and transaction management in Spring
- @Restcontroller vs @Controller
- @SpringBootApplication
- How to create the rest API in spring boot – complete flow
- What are microservices?
- How do microservices communicate and discover?
These were the questions that were asked, some questions I am not able to recall. Hope this helps.
