3 technical rounds with questions on Linux , database and telecom protocols. call flows, ss7 architecture. tomcat , configuring application in tomcat, port numbers, understanding of the current role, management skills

My interview happened entirely over telephonic conversation. It was 1 hour long interview where in which I was asked more about what ever I mentioned in my resume majorly. After the first round, HR called me after 2 days and asked general HR related questions. Once that was done, a form was sent for filling and then the offer letter was mailed.
