I applied directly on their portal.

Round 1 - Screening Round(30 mins)

Expectation was to know my tech stack and how well I know my project a lot of questions around my resume, my interest in tech.

Round 2 - Technical Round(30 mins)

First interviewer started with my resume.

Q. DSA Question :
List of unique positive n numbers
{1,7,3,5,8,21,23,0} pair of number having sum as m = 8;
output = {{1,7},{3,5} ,{8,0}}

Q. Improve the given code
class SpecificCatches {
static void risky() throws IOException, NumberFormatException { /* ... */ }

public static void main(String[] args) {
    try {
        risky();
    } catch (Exception e) {
        // handle  problem
    }    

Q. Stream on Java
// Problem: From a list of integers, filter out even numbers,
// square them, and collect into a new list using Java Streams.

import java.util.;
import java.util.stream.
;

public class EvenSquaresProblem {
public static void main(String[] args) {
List numbers = Arrays.asList(1, 2, 3, 4, 5, 6);
// 4,16,36

    // TODO: Use Stream API to get list of squares of even numbers.
}

Then different questions on SprinBoot. The questions were mostly scenario based and they were trying to test my handon knowledge.
I fumbled a lot.

It didn't went as expected.
