Ericsson interview questions

I was selected in a campus interview. Filled an application form for it. Then in few hours we had an online test that was basic aptitude. Difficulty level was neutral. Then we had a GD round ( 10 people at a time). Third was a technical in person interview. Asked basic networking questions. And fourth was a general HR round which was just for name sake.

Tough multiple rounds of technical discussions. I was asked to draw diagrams on the white board. They asked me to give a quick test on laptop (test was from javarach.com). They have given me some critical scenarios which needs to be resolved immediately.
