Round 1: TCS conducted an aptitude and verbal reasoning test on 3rd Oct 2020. The next day on 4th Oct, a coding round was conducted. 2 coding questions were asked. Each question involved public and private test cases. 

  1. The first question was very simple and just involved the application of if-else.
  2. The second question was a little tricky and was related to pattern printing.

I solved the first question completely and public test cases of the second question. Scorecard was made on the basis of performance in both the test. After this, I got a mail from TCS on 15th Oct for a final interview. My interview was scheduled for 16th Oct at 11 am. 

Round 2: First I was asked to show my gov id proof, and then he asked whether I have any current backlogs or not.

It was a panel of three members.
