The process started with the recruiter contacting me.The first interview was a technical phone screen with the Team lead, involving questions around network fundamentals, coding challenges, routing fundamentals. After this were 2 phone interviews with Network engineers, testing my knowledge on routing, switching and the depth of knowledge in these areas. This was followed by an on-site interview which is where they revealed that they expect Web development skills, knowledge of Big-data etc. Which is what eventually led to them not extending an offer.
