It was a good process. There were 3 technical rounds and 1 managerial round in total. FIrst round he asked about networking and shell scripting. And some linux administration questions. In second round, they asked medium level coding questions and more difficult networking questions. Third round was a little cool off but it went on for like 30/35 minutes where he asked about my projects and walk through of my resume. Then in managerial round the manager asked about logical reasoning, and how to tackle situations in the office.
