1.There were 3 technical rounds. Two of them were compulsory and based on your performance you were allowed for the third. 2.The job role did not involve any technical skills such as coding but they asked questions which you would find in interviews with Microsoft and Google. 3.As a fresher you would not be knowing the complex jargons around Linux but if you mention that in your resume be prepared for some questions you've never heard of. 4.Interviewers themselves are not too technically strong so even if answer wrong with confidence they'll consider it correct ;) (This excludes the last round which has no logic to the difficulty as per the technicality of the role you will work on..Apparently, the interviewer claims to be an ex-employee of Microsoft and will ask you questions from Geeks for Geeks and CodeChef level...So don't feel confident after two rounds....
