3. A program reads in 500 integers in the range [0…100]representing the scores of 500 students.it then prints the frequency of each score above 50.what would be the best way for the program to store the frequencies?

Since we need to score the frequencies of scores above 50, we can ignore scores below 50 and to index the scores above 50, we can subtract 50 from the score value above 50.

Interview Experience

Harsh Green

TCS NQT On-Campus Interview Experience

  • Name: Harsh
  • College: Indian Institute of Technology, Chennai
  • Branch: Computer Science and Engineering
  • Type of interview: ON-campus Interview

Student Interview

I am a computer science student and wanted to join an MNC like TCS. Last year when our placement cell informed about the TCS on-campus drive in our college, I applied immediately for it. I collected materials from my seniors. I asked them about the difficulty level, and types of question asked in the interview round. They asked me to refer PrepInsta website. I found a lot of sample questions and interview experiences on the site, which helped me a lot during the entire placement process.

The eligibility criteria for the interview was:

 

  • Qualifications: Full-time graduate from B.E/B.Tech/M.Tech./M.Sc./MCA
  • Eligible Stream: Eligible Stream
  • %Criteria: 60% marks throughout academics
  • Backlogs: 1 active backlog accepted
  • Academic Gap: Not exceeding 2 years

Rounds

The TCS conducted its recruitment process in three rounds. The first round was the written round which involved an online test, followed by two more rounds:

  1. Written Test Round
  2. Technical Round
  • TCS Ninja Interview
  • TCS Digital Interview
  1. HR Round

Written Test

The first round of TCS was made up of four sections. The first one among them was the English section, followed by the quantitative aptitude, programming concepts, and coding.

English: In this round, there were questions on sentence completion. I had to fill answers using the option provided with the blanks. The time allotted for this round was 10 minutes for 15 questions.

Quantitative Aptitude: The next section was Quantitative Reasoning. These questions were simple for me to answer and had thoroughly prepared them. The time given was 30 minutes for 15 questions. The questions asked were of time & work, profit & loss, number, decimal fraction, time, speed & distance, geometry, coordinate geometry, and blood relations.

Programming Concept: The test had some questions from a programming language. The topics asked were Iteration, recursion, procedural vs. Oop, Algorithms, and Data Structures. 20 minutes were allotted for 10 questions.

Coding: In this section, only one problem statement was given, and the time allotted was 30 minutes.

Technical Interview Round

The second was divided into two interviews:

  • TCS Ninja
  • TCS digital

The TCS Ninja interview was for about 25 minutes and included questions on:

  • Properties of intrinsic semiconductor?
  • What is the concept of Oops?
  • Different types of modulation?
  • Difference between C and C++?
  • What is the highest precision Datatype?
  • Why do I want to go to an IT job?

The second interview round was TCS Digital interview. The interviewer first asked me the part of the framework I was handling. He then asked me to implement a concurrent mask and discuss the concurrency challenges.  He also asked me about the default constructor. The interview got over in 20 minutes, and I was sent to HR for the final round.

HR Round

The HR first asked me to introduce myself and then asked me some questions about:

  • My most significant accomplishment.
  • What most of the people like in me?
  • My hobbies and interest?

Finally, he asked me if I had any doubts or queries. So, I asked him about the training procedure. One week after the interview, the results were announced, and I was happy that I was selected.
