The interview process was very thorough starting from my first round. Don't go by JD, you would need to have deep knowledge of the concepts and much more skills than what is mentioned. I would not say it was very difficult but yes they want the Engineer to have knowledge on a broad spectrum of concepts. Just stick to basics and cover whatever you can. Round 1. 10 questions on linux, networking and computer hardware Round 2. Technical round on Networking Round 3. Technical round on Linux Round 4. Technical round on Hardware and DC(Data Center) HTH!

Recruiter emailed to discuss interview format and scheduling for two phone interviews. The interviewers then called at their scheduled times, each lasting between 40 minutes, and 65 minutes. Straight open ended questions, very vague, or very specific. Time for questions at the end. Follow up from recruiter several days later.
