Tata Steel Management Trainee (Systems) Interview Experience | On-Campus 2021

TATA STEEL visited our college for hiring at management trainee systems post, CS and IT branches were eligible with >6.5cgpa. A total of 67 students appeared for the written test.
The written test was conducted on mettl platform which overall consisted of three major sections
1. Aptitude-It consisted of numerical, logical, verbal and data interpretation sections. Questions in this section were medium to high level. Following Arun Sharma apti book would be really helpful. Also give quite a bit of free mock tests online.
2.Coding- The test consisted of 1 coding question of 30 min, the difficulty of the question was a bit above medium level, I got question of finding the total number of pairs of number smaller than the given number whose gcd is equal to 1, the numbers would start with 0, the question consisted of tricky edge cases and also the UI of mettl was quite different and these factors consumed me my extra time, however I was able to solve the question 3-4 mins before sectional deadline, a regular practice of cp based questions would ensure easy selection in this round.
3.Technical MCQ-The technical MCQ round was again comprised of questions from medium to high level c programming, os ,dbms, computer networks were asked. Referring GFG for this topics would be sufficient.Out of 67 students 7 cleared the written round(including me ;)) ).Next day we were scheduled for gd followed by interview
GD experience-we were given a topic “use of IT in manufacturing industries” and every candidate was allotted 2 mins to speak. Just think of little bit important topics and try to speak fluently, no one could deliver it excellently in such short span of time. Be calm and confident. 
After GD, interview happened on microsoft teams which went on for nearly  45 mins.
The first and foremost interview question which was asked to me was “Tell me about yourself”.

2. Technologies used in project, and also the approach used for making the entire project(both frontend and backend).
