I applied in-person. The process took 1 day. I interviewed at Netsat (Dubai) in Jan 2018
Interview
2 Phone Screens and One onsite interview.Interviewers are not expecting straightforward answers.They need you to explain the theories from bottom to top. They keep asking you questions from a section until the point you can't answer anymore. When you stuck they do change the topic and ask questions on a different topic and continue to deep.
Interview questions [1]
Question 1
Explain what goes through the OSI layer. How do routing and ARP work? What would be the most difficult thing that you have encountered at work and how did you resolve that issue? Tell me about a time where you recommended something that was entirely different from what the customer wanted.
