FIS interview questions

First round was telephonic round. I was shortlisted on the same day and was called up for Managerial round the day after as the HR person told me that they do not want to wait up and the positions needs to be closed ASAP. The 1:1 was a good 1 hour interview with the manager and was told that HR will revert with the interview feedback. Till now no response has come. Called up HR and the person did not pick up the phone. Later I followed up on email - no responses; and the mobile number is also switched off now. They should reply to the candidate's follow up as they are investing time and energy for the interview process. The candidates are being taken for granted. If the candidate is rejected let him/her know. Very unprofessional. Hugely disappointed.
