STEP 1 : Clear TCSNQT
based upon your performance on TCSNQT exam , TCS will be offering 3 various roles with different pkg's.
ninja - 3.36 lpa
digital - 7 lpa
prime - 9lpa
I was shortlisted for prime role.(I solved 2 coding questions (easy + hard) & performed really well in Advanced Quant & Reasoning round as well) for aptitude rounds they provide virtual calculator .
VVI topic imo -> string , matrix , complex pattern , problems based on list & set .They don't ask tree or graph coding questions much.
I will recommend practice these topics from interview 75 , top liked 100 , interview 150 nearly impossible to get questions outside these study plans .
My papers ->
you are given a matrix filled with non-zero elements. Create an upper tri-angular matrix out of it . Question itself stated what an upper tri-angular matrix is . - easy
68 - text-justification . 6 - zig-zag conversion close to the mixture of this two . - hard
STEP 2 : Clear Interview
According to my experience ,
ninja - mostly asked HR questions .
digital - well mixture of HR & Technical .
prime - mostly asked Technical based on CV & outside .
for digital & prime you are expected to be promt & really knowledgable.
Questions I was asked
Introduction. (prepare & reharse)
explain your projects. (start with most complex one)
follow up question from projects , which version of java i used & why , scope of enhacement & drawback etc .
lambda function .
what is ACID properties
Normalization
What is NoSQL
what languages you know apart from Java
which language you want to learn in near future & why
what are the advantages of Kotlin upon java .
OOP concept (4 pillars) , explain them briefly.
what are your hobbies .
I am an android developer , everyone's interview experience differs according to their profile .
selected for ninja role.
I applied through college or university. I interviewed at Tata Consultancy Services (Madras)
Interview
First we have to cleared the TCS ION test. If you can able to solve both the coding questions then you can eligible for the Prime role. The interview was quite easy. The interviewer was made me comfortable. The offer letter was issued within a week.
I interviewed at Tata Consultancy Services (Calcutta)
Interview
The interview started with a brief self-introduction, followed by questions about my coding experience, including how many coding problems I had solved on the NQT platform. The interviewer then asked me to write a sorting algorithm on paper, explain its logic, and modify it to sort the array in descending order. After that, the discussion moved to C programming concepts such as `malloc()` and `calloc()`, including their differences and use cases. The interviewer also asked fundamental DBMS questions and SQL queries, including writing a query to find the second-highest salary from an Employee table. Later, I was asked to explain the projects mentioned in my resume, focusing on the technologies used, my contributions, challenges faced, and how I solved them. The interview concluded with several situation-based questions to assess my problem-solving ability, communication skills, and approach to handling real-world workplace scenarios.
Video Screening followed by the aptitude test.Aptitude is a mid range test.Email response is bit later..and after interview we need to followup many times to see the results..I waited almost 1month
