I applied through a staffing agency. The process took 3 days. I interviewed at NETSCOUT in Dec 2010
Interview
Impressed by the interview process. Most of the rounds will be technical interviews. Even managerial round will have technical questions as most of the managers are technical people. You should have the Networking domain knowledge to clear the interview as they will ask right from basics to advanced topics.
Interview questions [1]
Question 1
In technical: Complete OSI reference model and protocols under each of the layer.
Management: Most difficult case to handle in previous organization and how I handled it... how it could have been handled better
