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.geeksforgeeks.org/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.
