The duration of this round was around 20 minutes and there were 40 questions in total. This round consisted of standard mathematical, logical aptitude questions. Aptitude questions based on directions, speed and time, profit loss, etc. were asked. Out of 40 questions, around 15 questions were diagram based questions like finding the odd one, predict the next pattern, etc.

The Second Round is an Online coding test that lasts for around 30 minutes to 1 hour. It was held on the coder byte platform. There were around 5-6 MCQs and 1 Coding Question. MCQ Questions - Predict the output, find errors, Simple language-based questions etc. The Coding Question was from Arrays, Strings, etc. For Example, You are given a string like “ONE PLUS THREE MINUS TWO” and you will have to give output as “TWO”

They will give you a frontend role based on your performance in Interviews Rounds.

This round was scheduled with the SDE-2, we started with the introduction than he jumped to the dsa questions. First question he asked me was leetcode 3 sum problem, we discussed the approach than I wrote the code for that problem. Second question was of arrays and maps I didn't remember the exact question but that was also some modified version of k sum subarray. Than he asked many questions related to oops, I answered most of them than he asked me for any qiuestions and we dropped the call.

Q1. 
Triplets with Given Sum Problem
Given an array or list ARR consisting of N integers, your task is to identify all distinct triplets within the array that sum up to a specified number K.
Explanation:
A t...read more
Ans. Brute Force
• The most trivial approach would be to find all triplets of the array and count all such triplets whose ‘SUM’ = 'K'.
• We can find the answer using three nested loops for three different indexes and check if the values at those indexes sum up to 'K'.
• Create a set  to keep the track of triplets we have visited. Run first loop from i = 0 to i = ‘N’ - 3, second loop from j = i + 1 to j = ‘N’ - 2 and third loop ...read more

Q2. 
K Sum Subset Problem Statement
You are provided with an array arr of size N and an integer K. Your objective is to compute the maximum sum of a subset of the array such that this sum does not exceed K.
E...read more
Ans. Brute Force
In this approach, we will iterate over all the possible subsets of the given array, and then we will find the maximum sum subset whose sum is not greater than K.
The total number of subsets of an array is 2^N or 1 << N in the bitshift operator.
 
Algorithm:
• Set N as the size of the arr
• Iterate i from 0 to 1 << N
  • Set currSum as 0
  • Iterate j from 0 to N
    • If i AND (1 << j) is not 0
      • Add arr[j] to cu...read more

This round was arranged with the Engineering Manager, we started with the introduction then he asked me to explain my project, I did that. After that he asked me one pattern question, I coded that than he asked me one more array question of finding mean, mode, median, I partially solved that question. Than he asked me for any questions and we dropped the call.

Q1. 
Diamond Pattern Grid Problem
Create a grid pattern of size R rows and C columns, where each cell contains a diamond-like shape of size S. The diamond shape is made with characters ‘/’ and ‘\’ for the bord...read more
Ans. Brute Force
Approach: Since each diamond’s size is (2 * s) * (2 * s). So the total size of the grid will be (2 * s * r) * (2 * s * c). So we will iterate in all the points on the grid and use some basic algebra(modular arithmetics) to find the diamond to which this point belongs. Then we can identify the type of location(i.e. either this point is a boundary or not) as we can divide the diamond into four equal parts(top-...read more

I had the flexibility to schedule it according to my time zone as the internship was Singapore based so I scheduled it at 9 am in the morning. The environment was similar to pair programming where the interviewer was a software enginner at stripe and asked me to code on any IDE with my screen share enabled. He shared the question on some online coding platform so it depends on you whether you want to use the coding platform or your own IDE. My language was python. The question was to figure out the optimal way to set the servers so that the servers are down for the minimum. One interesting part was to write the unit tests according to check the code on various test cases. I didn't know unit testing in python that time so it left a bad impression definitely. Other than the interviewer was really nice. After the interview ended, he told me about my shortcomings and also told me to learn about unit tests and testing.

Q1. 
Anagram Pairs Verification Problem
Your task is to determine if two given strings are anagrams of each other. Two strings are considered anagrams if you can rearrange the letters of one string to form the...read more
Ans. 
The task is to determine whether two given strings form an anagram pair or not.
• Check if the lengths of the two strings are equal. If not, they cannot be anagrams.

• Create a frequency map of characters for both strings.

• Compare the frequency maps of both strings. If they are equal, the strings are anagrams.

• Return True if the strings are anagrams, False otherwise.

The first round is an aptitude assessment that consists of coding questions focused on dynamic programming, as well as medium to hard level aptitude and reasoning questions.

The second round focuses on coding and consists of data structure and algorithm questions related to arrays, linked lists, basic Java concepts, strings, and project-based questions from the resume.

The third round also consists of coding, which includes challenging data structures and algorithms questions based on graphs, trees, multithreading, and difficult SQL-based questions.
