There is no sign to inform you where to go. So must ask around. Took a number and the counter will asked for your photocopied transcript and education certs. Asked to sit down and then, filled up the online form. Again, ask to wait until the interviewer calls your name to enter the room. Approximately 15 mins of interview

There will be at least 1 to 2 interviewer. You will need the standard documents such as education cert and Ns cert. Prepare resume before hand as you will need to submit it on that day itself through their website portal.
