The first round was an online test. The test had three sections- Technical, Quantitative Aptitude and Verbal Aptitude. The technical section had very basic questions about C, C++, Data Structures, Operating Systems and Networks. Quantitative Aptitude and verbal was no different from the ones conducted by many other companies.
The second round was a Group Discussion. A group of 8 members moderated by three representatives from the company. The topic was very generic. We were asked to talk about "Social Networking- A boon or a curse".5 out of 8 from our group, got through to next round.
Third was a technical interview. A one-on-one interview. 90% of the questions were on Networks. He asked me each layer. Some practical problems. The remaining 10% was for UNIX and my project work.
The last round was HR. This round was pretty easy. No stumping questions or grilling.
