Telephonic and Personal interview interview was very unprofessional ,Authority keep u wait for a long time.Any one with low iq can clear the questions.But i went through many unwanted rounds of interview.Preparation is not required.After all this you have to wait for approval from the top management which is the worst part and may even take months of waiting which i had experienced and there is probablity of 80% that the candidature will be accepted and 20% you may be rejected.Even though you are selected no trainning will be provided.Overall worst Experience..
