The complete interview was a very long process. First step was an hour long we were called for a technical written test. Second step in the process was a day long interview where they started off with a short presentation then some team building activities like building with LEGOs and treasure hunt. Later after lunch we had a comprehension test, hands on test with their software(setup internet and firewall manually), communication exercise, manager interview and lastly Technical Interview( Really hard).

Group interview, then 2 one-on-one with managers. One is technical, the other is customer service based. For technical interview, study some YouTube videos on OSI, routing, switching, firewall etc. Pretty easy if you know this stuff well.
