TCS Codevita is a programming contest conducted by Tata Consultancy Services every year. I attended TCS Codevita Season 11 which was held on December 9, 2023.

Codevita Round-1: In the contest, there are 6 questions. From this, I have solved one question. People who can solve medium-level array questions from geeks for geeks and leetcode can clear this round.

Codevita Round-2: The contest mostly focused on Data Structures and algorithms. I have not cleared this round.

TCS-Tag test: After clearing codevita round-1, this test is taken at the TCS ION centre. This test was held on March 8, 2024. The test consisted of 2 questions one question for 25 marks and the other question for 50 marks. The marks for questions are awarded based on several testcases cleared. Each question has 2 sample test cases and 5 private test cases. Marks are awarded only for private test cases.

After clearing the TCS-Tag test I was notified of the TCS Digital interview at TCS Hyderabad. For this interview, I have referred GeeksforGeeks interview experiences and they helped me a lot to understand what the company expects.

Similar to previous experiences mentioned in GeeksforGeeks, the digital round consisted of Technical, Managerial and HR rounds simultaneously. I strongly recommend being thorough with your resume since most of the questions are based on it and you must be able to explain the techniques and algorithms you have used in your project and justify them properly.

Technical Round:

1. Explain about your projects.
2. Explain how does k-means algorithm works and when it stops its iteration. (It was included in my project)
3. If you were to guide a beginner in learning programming which website, would you suggest?
4. Explain exceptions in Java.
5. Explain about Polymorphism in Java.
6. Explain about Run time exceptions and Compile time exceptions in Java.
7. Differences between Power-BI and Tableau. (Mentioned as BI tools in the skills section of my resume).
8. Reverse a string and check if the given is palindrome or not code.
9. Arithmetic Exception and Null Bound exception in Java code.
10. SQL joins

Managerial Round:

1. Introduce Yourself and the conversation went about family so they did ask some questions about family background.
2. Explain your strengths and weaknesses.
3. Is this your first job interview?
4. Why would you like to join TCS?
5. Are you willing to learn new technologies for the project?

HR Round:

1. Is relocation possible?
2. Is working in shifts okay for you?

All the rounds will be easy if you are thorough with concepts, also try having mock interviews, this can help you understand points where you could be struck and also helps you explain your concepts clearly. All the interviewers were friendly and comfortable to speak with.
