I applied online. The process took 1 day. I interviewed at Tata Consultancy Services (New Delhi) in Jun 2024
Interview
The overall interview process was quite delayed, so patience is definitely needed. The interview itself focused mainly on behavioral and technical questions.
Behavioral Questions:
These were pretty standard — they asked about my strengths, weaknesses, how I handle pressure, and situations where I worked in a team or solved a problem.
Technical Questions:
Most of the technical questions were from core subjects like OOPS concepts. I was asked to explain things like method overloading, inheritance, and polymorphism.
Overall, the interview was straightforward but required a good grip on fundamentals and clear communication skills.
