My interview process might be very different from most people's because I interned with the group a year ago. They ask standard questions about school: what classes I took, what I liked about it, etc. They asked me to write a C programming counting the number of 1's in a binary string.

HR contacted me during the beginning of February from Linkedin. After a brief introduction. I was given a first-round telephone interview. The Hire Manager asked me a lot of EU project questions because I'm now working in the United Kingdom. He also expect to know my system architecture background. After 30 minutes ' talk, HR informed me that I will go through the screen phone interview. A principle engineer contacted me and asked the questions including an algorithm and KVM / Xen related challenges.
