Managed to clear the round and I had was told wait for some time. That “some time” came at 7.00 PM when 2nd round interview(project management) was conducted .I Answered all the questions and the interviewer was very much positive. But ultimate shock came after that when a I was taken to another room where I was told-“We have found you technicaly sound and match for TCS, but our existing project requirement does not require an professional with such high experience( I had 8 .5 years). We are keeping your profile in our internal portal so that whenever there is a match we will call u for HR round. Since you are not rejected you can keep applying to TCS, your profile is not barred” . I asked him- why did you ask me to remain here since 2 PM then? You knew that I had experience of over 8 years but still you taken two round of interviews for nothing? He simply gave me a smile. I am already working in a PSU and thought that people of PSU indulge themselves in dirty politics but as organization they are good. I never expected this kind of unprofessional attitude from TCS.
