TCS Digital Interview Experience 2021

We applied directly on the TCS Next Portal site as my college comes under the premium list of TCS. So, we were allowed to directly give the ONLINE CODING ROUND.

Round 1: Online Coding Round

Section 1: English 

This section needs a good understanding of English words, comprehension questions took more time while the one-liner questions went smoothly. (Suggestion: Start practicing comprehension questions now )

Section 2: Advanced Quant

If your Mathematical skills and logical thinking are good then this section will be a smooth walk, If not then It will become the toughest section of the whole exam. In my case, I did well in this and completed all questions in this section. (Suggested topic-time/distance, work-time, algebra)

Section 3: Coding Section

Basic or Medium level questions were asked. 

1. Given a string, check if all the letters of the alphabet are present in that string or not and print all those alphabets that are not present. I used the set concept for this.
2. This one was on Dynamic Programming.

I managed to solve both the questions. Suggestion – No proper input, output format was given, so keep 10 minutes in hand for this.

Suggested topic-All standard dynamic programming problems (LCS, LIS, 0/1 knapsack, edit distance, max sum sub-matrix, etc.)

The list of selected students for the interview came 1 week after the coding round. 188 were selected from my college out of 450.
