It was overall 4 round procedure
1st Round (1 hr)
in this round we have to solve two coding question ( which is leetcode easy based on array and string concept ) other than coding some MCQS of DBMS, Java Script , OPPS .
2nd round (1 hr)
it is a case study round in which you have to write approach not the whole code or algorithim on paper with in the given time you have to scan or upload the answer. in this 3 questions had been asked in which you have to answer only 2 ( in my collage 2 question from DSA and 1 from DBMS has been asked i did both DSA problem )
it was not an elementary round.

in this round i have been asked basic concept of OOPS(4 pillor, constructor and destructor, friend class),basics of C & C++,some SQL command ( 2nd highest salary), two - three basic coding problem ( intersection of element in two array , middle element of linked list , binary tree), small discussion on project which i mentioned in resumme and after that almost 40 min discussion on the question of last case study round the approach or algorithim which i submitted and like how you started thinking on this problem other than that what can we do ? mens complete discussion on both problem.
