It was 3 stage interview, HR screening ~30 min, 1-Technical Interview ~1.30 Hrs, and again 2-Technical interview ~1 hr. HR lady was really nice, every technical round was very very nice and polite. But I am really disappointed as they didn't about my final results despite of sending multiple emails. 1st technical round they asked almost every layer network protocols, Basic Linux, Live python coding, and questions related to my work experience. In 2nd technical round, they asked me some questions neither were from my resume nor from Job Description. Be ready for some surprises.
