Tata Consultancy Services Seniot Software Engineer interview questions

Smooth and professional .. they asked questions from the resume mainly related to job and common skills. Then the asked some advance level questions. They also asked some situational questions and some related to my previous exposure

Too many time i give interview in TCS but i don't know what they are looking for in candidate if you are give a correct answer still they think a lot and reject candidate. if candidate selected then HR will not call you she directly contact via email if you any doubts still we have to wright email to HR that process also taking more time to release the offer i do not like that process. Not a prompt response.
