I applied online. The process took 4 days. I interviewed at Tata Consultancy Services in Nov 2024
Interview
There were 2 set of Technical Rounds and the both were almost for 40-45 mins each. My experience with The Interview process is neutral since HR ghosted without any proper feedback. I almost answered all the questions asked but then also none of the HR came back to me with proper feedback.
