Tata Steel Management Trainee interview questions

I applied through college and got a chance to got interviewed on 24th dec. 2021. The process was consist of resume shortlist (may/ may not) followed by :- 1. Aptitude test- consist of Quantitative, Qualitative and verbal reasoning. 2. Group discussion- we have been given a topic and was allowed to discussed for15 min. 16 people were shortlist for GD round. 3. Interview- 9 people were shortlisted for interview round. There were 4 Panel member including HR. As soon as i entered the meeting hr told her name and further started my interview by Introduction. I got a complement by hr for the introduction part ( she told as i covered very nicely all the area ). then one of the 4 panel members asked to explain project. as i had mentioned Home Automation ( Automated solar Panel, Automated door, Controlling light bulb intensity using Google Assistant and some small features like Fire alarm And automating street light and protecting house by a password) then he asked what was your role/ which work you were given. Although i told that i every team member worked on every features but again he asked to choose a part on which you worked. I choosed Automated Solar panel and he was about connection and components used and he further asked about working of components (Servo motor, LDR...). After project part he asked Polymorphism (c++ was in my resume) then another panel member started asking. He also asked from solar panel part ( working of servo motor, what is input and output and some basics part ). difference between DDL and DML from SQL . and then he started asking something that i had never heard those terminology (might be from computer network) not only from me but from all the interviewee ( as other interviewee told me personally). After this my interview was over. Interview goes around 17-20min only. 4 people were selected including me. NOTE- this management profile is software oriented not totally software because just asked aptitude in test and project+ some basics oops concept in interview. Even i mentioned python but not asked a single q. And consider solar panel part as just a cardboard attached with motor and a sensor (that response if light intensity changes) and nothing more in depth about it.

Tell about yourself. Brief your academic project works. If you have any work experience then questions are asked related to that also. Basic technical questions and HR questions.
