Well today I am going to explain my TCS Digital Interview Experience.

Our college got schedule on DEC 2ND-2020 for TCS Digital Interviews. My interview was at 10.25 AM , some students will have nervousness when attending for interviews . I too had nervousness when I was giving my first interview but TCS Digital Interview was not my first interview. Before that I had given interview for other companies like Cognizant, Hexaware, Postman, Infosys and few others.

If you have interview experiences you will gain some confidence of giving interviews without any fear. It's a better practice to give mock interviews. Well let's dive to into the interview.

TCS Digital interview was online due to the covid 19 pandemic . My slot was at 10.25 AM , and it was on Cisco Webex .

Really the tech interviews won't happen at the said time, in my case also same thing happened.
