TIps for BPO interview - Tech Support

It's quite boring sitting in home for a long time, so I just want to go to a Tech Support Interview in BPO. Got reference through my friend and went there on monday. I don't want to mention the name of the BPO. Just went there to get some experience on BPO interviews. I just want to attend for Tech Support because my friend's told me that I could get some good questions to answer. Most of the people who came for the interview with me were doing their CCNA course. The questions were based on these topics,
Routers and switches, IP address, MAC address, PING command, OSI layers and functions of each layers, SCSI, DNS server, MODEM and Firewall. That's what i remember, so if you are attending for Tech support interview in any BPO prepare in hardware and networking concepts that will surely help you. Please put your aggregate below 75 or even below 70, because i got rejected for my aggregate only. So please be careful in putting marks in your resume, because every BPO HR will see your longevity of service for the company then your talent. They know that a person with good aggregate will not be in work for more than three months and BE graduates are their last choice while selection.
