On 27th January received a message from our placement cell that out of 21 students 7 students have been selected for Innovator role and I was one of them.

I got my offer letter on 12th February from NextStep portal. 

My Tips:

  • Be Confident.
  • Revise the projects that you’ve mentioned in your resume, you’ll get a lot questions from those.
  • If you don’t know the answer, just tell them what you know and also mention them that you aren’t aware of exact answer. Don’t say NO immediately to any questions that you don’t know.

It is a good thing that TCS upgrades your offer if you cleared the test. I got upgraded from Digital to Innovator. So, Don’t lose hope if you are having Ninja/Digital offer from TCS.
