I was interviewed in Sep 2020.
Round duration - 40 minutes
Round difficulty - Medium
Data structures were asked like linked list and stacks. Hashmaps were also there. some basic questions of DBMS were asked and the interviewer asked if i know networking for which i said no. After that there was a 5 minute simple straightforward round with H.R
Tip 1 : Practice maximum questions of linked lists and stacks.
Tip 2 : DBMS concepts should be crystal clear.
Tip 3 : If you are not able to complete something in-depth, clearly mention that to the interviewer.
Tip 4 : Practice a mock interview and try to solve any random question in front of your friend.
Tip 1 : Mention maximum projects you have one and be prepared to explain them.
Tip 2 : Don't mention anything you are not confident in.
I was interviewed before Sep 2020.
Round duration - 90 minutes
Round difficulty - Medium
The round consists of 3 coding questions and the test was conducted on mettl platform. There was no sectional time limit for the coding questions. Every student got randomly 3 coding questions and none of the students got the same set of questions. The test was online with audio and video both on for continuous monitoring.
Round duration - 50 minutes
Round difficulty - Medium
This round was based on data structures and some discussion regarding the projects. The interviewer was very calm and listened very carefully to the solutions. There was a lot of discussion on my projects and the interviewer seems to be very interested in knowing about the workflows of my projects.
Round duration - 50 minutes
Round difficulty - Medium
This round was also based on data structures and the interviewer was not responding as much as in the first round so that I should think on my own that whether I am on right track or not. In this round also there was a deep discussion on one of my web development with machine learning project. So don't panic in these situations If the interviewer is not responding much because he is noting down every tiny detail of your written code.

This was an HR/Coding round and was the final one. The coding question was to find the nth node from the end of the linked list which is similar to the one asked in the previous round. The interview started with 2-3 HR questions and after I answered all of them, there was a serious discussion on my projects like why did you chose this project, what are its advantages, was it able to solve the existing problem. I answered all the project related queries very calmly and he was satisfied.
Tip 1 : I would suggest practicing as many questions on data structures and algorithms as you can because it is the question practice that would help you in building your concepts strong. I practiced a lot of questions on InterviewBit and completed all modules of data structures and algorithms because there you can find the recent interview questions that you should know.
Tip 2 : If you have time for your interviews, I would recommend going through Leetcode as it has a good variety of questions sorted on topic wise difficulty level where you can try to solve at least 20-30 questions for each data structure and algorithm. Moreover, you should regularly participate in the weekly contests happening there so that you could know about your weak areas to improve.
Tip 3 : Along with coding you should be clear about some basic concepts of Operating systems and Databases that would help in your interviews. One more thing is that do some good research about the company's goal and vision and be prepared to ask some company-related queries that show your interest in the company.
Tip 1 : Your Resume should consist of mainly skills, projects, and achievements. Projects would play a crucial part in your interview and you should have at least one most relevant and good project that shows how strong your concepts are in development.
Tip 2 : The most important tip is that never lie on your resume and like If you have worked upon some technology for the project part only and don't know the proper depth you could write basics only in your resume.
I was interviewed before Sep 2020.

This was my first interview and I was a bit nervous. The interview was conducted on Microsoft Team. He told me to share my screen and write the pseudo code on notepad. The interviewer was very friendly and also gave me hints for the question. However, he mostly focused on optimization of the code. At the end of the question, few questions related to Operating Systems were asked.

This was my last round and I was a bit tensed. It was an HR round. The interviewer was very professional. He discussed and asked questions about my various achievements, my interests apart from the technical field and also asked about my projects. I made sure to answer all the questions confidently and calmly.
Tip 1 : Having a grip over Data Structures and Algorithms is very important. Have your concepts crystal clear and then pick one coding platform( for example, leetcode, InterviewBit, CodeZen, GeeksForGeeks) and try to practice around 7-10 questions everyday with varying difficulty and different topics. I completed around 200+ questions on leetcode, 200+ questions on geeks for geeks and around 30-40 problems on InterviewBit.
Tip 2 : After writing code for a particular question try to analyze its time and space complexity. Think about how you can optimize your code further. Also refer to the editorials and compare your solution with it. Interviewers ask a lot about further code optimization. Hence, instead of trying to solve more and more problems, try to analyze a question completely and understand the concept behind them.
Tip 3 : Along with coding, study about OOPS. Coding Ninja's Data Structures and Algorithms course helped a lot in preparing the OOPS concepts specifically. Also, OS and DBMS must also be studied. You can refer to GeekForGeeks articles for these topics.
Tip 4 : Keep participating in coding contests. It helps you increase your speed. I participated in almost every Leetcode Weekly Contest which helped me keeping the track of my improvement.
Tip 1 : Do not fake any skills, projects or achievements. The interviewer gets to know about it by asking questions to you.
Tip 2 : You do need to have a long list of projects. Any 1 good project with proper knowledge of it will also do good. Similarly, you do need to have many skills to be listed down. Few skills but with proper knowledge is great.
Tip 3 : Try to write achievements which proves your technical skills, communication skills, leadership quality or teamwork.

Tip 1 : Begin early, but do not regret your timing.
Tip 2 : Be consistent. Do something everyday. Small progress every single day is better than no a rushed, hard-work day and then nothing for a week
Tip 3 : Relax and don't stress. Never doubt even if you don't see progress or have to face rejection. Trust your timing.
Tip 1 : Include only genuine information.
Tip 2 : It should never be of more than one page

My interview was at 9:00 am. The interview was conducted on Amazon Chime and my webcam was on. The interviewer also asked me to write the code on a document which can be edited by both me and the interviewer. The difficulty of the questions was of medium level. I was asked 3 coding questions along with 2 questions related to OOPS at the end. The interview ended with the discussion of one of my projects. The interviewer was good and also gave me hints wherever required.
Tip 1 : You must have a grip over Data Structures and algorithms. Your concepts must be crystal clear. Pick one coding platform and try to practice at least 7-10 coding questions everyday. I completed around 200+ questions on Leetcode, 200+ questions on Geek For Geeks and around 30-40 questions on InterviewBit.
Tip 2 : After attempting any coding problem, analyze its time and space complexity. See, if you can further optimize your solution. You can always check the editorials and compare your solution with it.
Tip 3 : Apart from coding questions keep studying concepts of Operating Systems, databases and object oriented programming. You can always refer to Geeks For Geeks articles for it. Also, Coding Ninja's Data Structures and algorithms course in C++ helped me a lot in improving my OOPS concepts specifically.
Tip 1 : You do not need to have a long list of projects on your resume. One good project with proper knowledge of it will do good. Similarly, do not list down several number of skills. Few skills but roper knowledge of them are enough.
Tip 2 : Do not fake anything on your resume. The interviewer gets to know about it by asking questions. If you aren't able to answer, it leaves a negative impact.

It was a pretty interesting round, in which i was asked to design a solution for real life situation.
Tip 1 : Start with making your basics strong about programming, which included basic data structures like array, linked list etc.
Tip 2 : Practice dry running the code with custom test cases, try to find the edge cases by yourself
Tip 3: Do not search for a solution until you have tried your best to think of it
Tip 3 : For reference you can reach to Interview Preparation Course of Coding Ninjas, LeetCode, Codezen
Tip 1: Have at-least one good project on resume, keep it to the point and do not fake it.
Tip 2: Add the skills section to your resume properly, highlight what's needed.
