Lengthy but thorough process. After I submitted my resume the HR rep called me for a chat to see if I was a good fit. He then organised an initial technical interview for me. He gave me high level understanding of what would be expected which was helpful. After that stage you go to the loop interview stage which consists of 4 or more interviews (I had 4) with a mix of technical and leadership based questions. You can do these on seperate days or on the same day. I did mine on the same day, they go for about an hour each. Preparation is key to all of these interviews. They're no easy fluke. Have notes prepared.

4 rounds of interview 1- Technical Networking 2- Technical Operating Systems 3 & 4 were Managerial From Technical aspect, just be strong with networking fundamentals and have a clear idea of how things actually work in networking. For Operating Systems round, just know basics of OS and some commands (from either linux or Windows, whichever you are comfortable with)
