TCS Digital Interview Experience (Premium College Drive)

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
time.


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.)
