Scheduled interview with NTT DATA white field Bangalore. Interview started at 10 and after waiting 2 hrs my turn came and initially I felt like interviewer was not interested to ask questions. Interview went for 20 mins and He asked brief about me, then asked some simple questions. He was not allowing me to finish my answer. He asked me to write some code once I started writing he told me not required leave it. If interview was happening just for formality please don't waste candidates time. We all seriously come to attend interview by keeping aside our other plans and interviewer like him just do time pass. After asking HR about feedback she told I was not good through technical. When interviewer not conducted interview properly then how he can decide about my technical knowledge.
