PROFILE

Aayush Garg
Education
Computer Science Engineering
7.7 CGPA

Preparation

Duration:
1+2 months (rigorous practicing)
Topics:
1. C++ basic Coding + Data structures knowledge (learned during the two years of college Courses + Coding Ninjas course of C++ introduction and C++ data structures) 2. OOPs + Pointers (best and complete material for interviews is available at Geeks for geeks) 3. Dynamic programming and Recursion best explained in (Coding Ninjas course) + (Youtube channel of Aditya Verma if you want free material ) 4. Graphs , Hashmaps and Priority Queues (again I found Coding Ninjas course to be super amazing) 5. Operating system + DBMS(theory part) (I found best material of Gate smashers (youtube channel)) 6. Networking (just required for very few companies) (I liked TutorialsPoint tutorials a lot (very concise and to the point ))
Preparation Tip

Tip 1 : Practice atleast(easy and medium questions from leetcode under(Top Interview Questions)) and all the questions from Gfg under(must to do coding questions for interviews))
Tip 2 : Don't learn each and every question you solved but try to solve question in a way that you can solve its variation during interviews
Tip 3 : Do one project(one is enough) which you can explain with full technical details (why you used this technology, and all logics you applied in implementation) 
Tip 4: Atleast read the round 1 (Coding round) Archives from (Geeks for geeks or Glassdoor). To get your mind prepared for the types of questions that company usually asks.(Coding round is the toughest Step in the whole Process to clear)

Application Process

Where:
Campus
Eligibility:
CGPA above 6 and no backlogs (there was no branch criteria for eligibility)
Resume Tip

Tip 1: Have at least one project which you have made yourself and you should know all the technical questions related to that project (I feel project domain hardly matters like web development or android or ML/AI)
Tip 2: You should Put only those skills in resume :
1. Which the company requires (eg if you know company doesn't require Networking domain knowledge so 
don't include it unnecessary if you are not much confident in it)
2. For on campus internships resume shortlisting is very easy so don't add anything unnecessary which might 
cause you pain during interview.

This was a completely technical coding round where I was asked to solve the problems of data structures.
The codepad where i was asked to code was fine,
The interviewer was very friendly and was helpful and understanding.
I also asked him about his work and experience in the company and some other questions.

Given a matrix mXn with integers filled in it. I was required to find the maximum path sum in the matrix starting from any element of the matrix. The condition as that I was allowed to move only right or down from any index(i,j).

You have been given an N*M matrix filled with integer numbers, find the maximum sum that can be obtained from a path starting from any cell in the first row to any cell in the last row.
