The company Visited our Campus and it had 4 Rounds. 1. Aptitude 2.Coding 3. Technical Interview 4. HR. 1. Aptitude: The questions were pretty simple, you can use any Online Platform Common Aptitude Questions to prepare for it. It was pretty basic. 2. Coding Round: This consists of 2 Coding questions and you need to solve any 1 out of them, to be selected for the next round. 3. Technical Round 1: Firstly you are asked to introduce yourself and they prefer students who know java or atleast the basics. I was not sure about my Java Skills thus I said that I don't know java much (Never do this, let the interviewer decide.) As I mentioned this, they asked me about my project and languages I know. Since my project was in ML, they interviwer didn't had much to asked. Thus they asked me What is Pandas ? Difference between C and C++? How does memory allocation works in C++ and what is pointers in C++ (I knew this in Java too, so I related this question and also talked about memory allocation in Java.) Since I was getting comfortable talking about java. The next questions asked were:- What is OOPS ? , Inheritence , Polymorphism with example. Is Java a 100% Object Oriented language ? what is Exception Handling in Java and how it is done? ( I was not able to answer this. Then they asked me questions related to Data Structures like:- What is queue and What is stack ? , and how they are different ?. After this they asked me what is Binary Search and to explain its logic. Coding Questions: Any Sorting Algorithm explain + code (I only said the logic as the code was long and they wanted quick answers) Factorial of a Number ( I was able to code this but it was not efficient wrt to time & Space) As I had some basic mistakes in my first Technical Round, Thus there was a conflict between my interwers (there are 2 of them) regarding my selection. Thus I was sent for a Technical Round 2, where all my peers directly went for HR. Technical Round 2: It started with my Introduction (there was Software Developer with 10+ year experience taking this Interview). This feels more like they were testing my logic. The Interviewer Specifically asked about 1 project from my resume, which was sarcasm detection. He asked me if we can build a Similar one to Detect sarcasm and bullying from a social media platform. If yes, then explain the concepts used and why? If my Models can run offline, if yes then how? They asked me to write a Function from Scratch to generate a random no OTP. (Note: You can't use any pattern or Calculation as it can be easily hacked), (Hint: You can use time) the interviwers tries to help you a bit here by saying either yes or no or sometimes some more hints. You have a 50 Floor building and 4 lifts in it. Give an algorithm that can make it very efficient such that I wont have to wait too long. (Here you might not recieve any help.) This whole Interview was more about giving the logic then a code. Then I was asked if I know Data Structures, If yes then exactly which. I replied with Priority Queue, Min Heap, Max Heap, Stack, Linked List. The questions asked from Data Structures were : List the Linear and Non Linear data structures from what's mentioned above. What is Linked List and how is it different from Array. If Linked List is stored randomly then how it is linear (here they try to confuse you but be strong with your conceptual depth.) Explain Stack to a 5 year old. (Make sure to include concepts of Push, pop, top, overflow and underflow.) I was able to answer all the questions without taking much time, thus my interviewer was really impressed. We later discussed the other Algorithms that exist in the 50floor and lift problem. HR Round: As usual this round begin with my Introduction, what I did during lockdown and in 3 years of my Engineering. The HR talked about the company culture and more info about the bond and the company. She asked why I want to be a Developer, What are my Long term and Short term goals, Where I see myself in 3 and 5 years. Then they asked about my Family background and Members thier occupation etc. I gave a feedback to the Interviewer that I didn't liked the part where Questions asked in 2nd Interview were way too difficult and advance compare to Round 1. Also all other peers of my college were selected on the basis of Common Interview and coding Questions (factorial, reverse a string/number, find maximum no in an array etc.) were I had to go through so Logical as well as Data Structures based questions only for a 4.5Lpa job.
