NA
Tell us about the written/online test. (Aptitude, Coding, Test Platform, etc)
The test platform was CoCubes. There was only one written test round that contains three coding questions related to DSA from the topics Tree, Array, and String. The difficulty level was medium and it lasts for around 70 min.
Describe your all Technical Interviews specifying number of rounds and details of each round (if any).
There were three technical rounds: 1st Round lasts for around 1-1/2hrs. They asked me to introduce my self first and, started asking me the basic concepts of C++ and OOPS. After that, they asked questions related to graphs and some problems related to the DSA topic. They ended the interview with a basic discussion of projects. In the 2nd Round, they asked me questions related to OS and DBMS, after those Hard level problems from DSA. In the 3rd Round, they asked me problems related to puzzles, real-life implementation of C++, after that they had a detailed discussion on my projects mentioned in my resume.
What were the key factors of your selection?
Key factors for my selection were : I finished my question of the coding round in 30 min. I was quite confident at the time of the interview. I kept revising major topics till interview date
What are the things students should focus on, in order of priority?
Students should focus on Data Structures and Algorithm, Operating system, and DBMS. These three major topics are really very important for Campus placement.
What would you like to advise juniors for cracking the HR round of this company?
Since there was NO HR round in this company, so in my opinion confidence plays a major role. One should know his/her strength and weakness.
Any advice to juniors for the technical skills they should develop?
Choose any option you want like do the development or go for data science but must do the projects. And side by side makes your DSA and Operating system stronger.
According to you, what role do extracurricular activities as well as participation in societies play?
In my opinion, extracurricular activities play a major in learning management skills and improving communication skills. As such, I was not of any society. I love playing basketball so focussed on that and selected for the college basketball team.
