This was an On-Campus Opportunity. I have registered for TCS in April and gave NQT on 6th of May. Later after 15 days interviews were scheduled. Process in detail as mentioned below:

TCS DIGITAL SELECTION PROCESS:

Round 1: NQT

This test was divided into 3 sections:

Section – 1

• Numerical Ability – (25 mins)
• Verbal Ability – (25 mins)
• Reasoning Ability – (25 mins)

Section – 2

• Advanced Quantitative and Reasoning Ability – (25 mins)

Section – 3 (2 Coding Questions)

Question 1: You are given an array of size n. Your task is to create a function called ‘most_repeated_number’ to find and print the number that occurs more than n/3 times in the array.

Sample test case

• n=9
• array = [1,2,2,2,2,3,3,3,3]
• output : [2,3]

Question 2: You are given an array and n integer that contain only 5s,6s,7s. Your task is to sort the given array(using swapping)

Sample test case

• n=9
• array = [6,5,5,6,7,6,5,6,7]
• output : 5 5 5 6 6 6 6 7 7

I could solve only 1st coding question and 2 test cases of 2nd question. After 15 days of NQT we got notified from college that we are selected for the Interviews.

Round 2: Technical Interview

They started with an introduction, requesting an overview of my final year project. Since my project involved AI and ML, they then inquired about the specific classifier I used, asking me to elaborate on why I chose it and how it functions, including an example to illustrate its application. The conversation shifted to resume-based queries, where they posed questions related to SQL and general database management theory. Finally, they tested my understanding of data structures by presenting a linked list problem and asked me to explain how it operates, along with detailing tree traversal techniques such as inorder, preorder, and postorder, using examples to demonstrate each method.

Round 3: HR Interview

1. Is the location suitable for you?
2. Why do you want to join TCS?
3. Are you comfortable with a pan-India location?
4. What do you know about TCS?

After a two-week period following the interviews, I received an email from Tata Consultancy Services (TCS) confirming my selection for the position and outlining the details of the role.

Verdict – Selected for TCS DIGITAL
