The first company to ever interview me turned out to be Tata Consultancy Services and I got selected for TCS digital profile via on-campus drive. I cleared the aptitude and coding rounds with flying colors. The only stage left was the interview. It was completely online conducted through cisco meetings. There were a total of 3 interviewers. Their videos were turned off, so I could not see them.

Team sign off: It was a pleasure talking to you and good luck with the results and your future!
Key points from the interview:
- Do not worry about not making a good first impression if you could not. Just progress with the interview and get better and better and most importantly “finish with a bang!”.
- Maintain a cheerful attitude even if you do not get positive feedback.
- Communication with confidence matters the most! You must be able to confidently say “Yes” if you know the answer and thus answer it. You should also be equally confident to say “No” and this is where your complete attitude is exposed.
- Make sure you have a complete idea of what you wrote in your resume and also be extra prepared to talk about something not mentioned in it.
- Ask questions whenever necessary.
- Questions vary depending on the assigned team. Hence, be prepared for anything especially the topics you mentioned in your resume.
