Usually almost all exams will have Written round and then a round of Interview. The Candidates who have cleared the Written test can check their results on the official websites. Then there will be an official notification released that shortlisted candidates need to attend for next round of Interview. Alternatively, while filling the correspondence address, you should give the address that you want to be contacted at. You will not be reached out at Permanent address but will be reached out only at Correspondence address.
