QOS Technology Network Security Engineer interview questions

I have attended QOS technology interview on 25-05-2018 through linked post. It was one of the best experience in my career life. 1. They will take written test based on basic networking concepts and it is description type questions. 2. They will call interview for those, who have secured good marks in descriptive type exam. 3. Technical round: questions will be from our resume mentioned topics and security domain based questions. 4. Second technical round: Again techanical questions are based on security domain.
