The process took about 1 month and a half.

I had two rounds of phone interviews and one final round of phone screen, all technical and one hour each.

The interviewers were very nice and friendly, and the entire interview process was pleasant.

This position requires candidates to have advanced knowledge of computer architecture and operating systems; the interview questions were also based on these.

I didn't get the offer, but I really enjoyed this interview process.

Hope you all the best. Please make sure you get all the basic concepts clear, such as cache coherence and NUMA architecture, before you go to your interview.
