they only had 1 technical round, Wintel basics, IIS basics and real-time issues and how was it you resolved them. Networking concepts, automation if any.previous scripting experience would definitely help

The technical interview was unusually aggressive. The interviewer was loud and interrogative in an attempt to catch me "looking up" answers to his questions. While I answered the technical requirements, towards the end I had a confrontation with the interviewer as I objected to what I interpreted as an unprofessional and disrespectful interaction.
