The written test happened on July 15th, 2019 as my college comes under premium list of TCS. So we were allowed to give the test directly.


Round 1:(Online test round)

Section 1: English
this section was comparatively easier than the mock test of digital.It comprises
of paragraph question which where time consuming, while one liner question were easy and taking less

Section 2: Quantitative Aptitude

this section was very tough for me question were really calculative and difficult to solve, but I managed
to do 12 out of 20.Suggested topic-time/distance, work-time, algebra.

Section 3:Programming Logic

this section was easiest the question were basic level and required understanding of loops and control statements
and variable.Suggested topic-loops, control flow, java, keyword in c++.

Section 4:Coding question
At first look the question seems confusing problem statement was like variation of 0/1 knapsack problem
but the statement was only different so it took time to figure out the logic.
Suggested topic-All standard dynamic programming problem(LCS, LIS, 0/1 knapsack, edit distance, max sum sub matrix etc.)

(NOTE:C++ STL is not allowed in coding test.)
