I was most impressed with the interview process! All employees with whom I interacted were friendly, positive, and had the process down to an art.

The technical interviews seemed to focus on discovering what I could do rather than exposing my flaws, which I feel is something the majority of other tech giants focus on.

Both interviewers made a really strong effort to encourage staying calm and having fun solving the questions.

I had a phone screen and two technical interviews.

I've heard that some interns do get an additional onsite interview after this.

The questions focused on testing my Linux skills and quickly solving small-scale problems, so you really need to know your Linux and scripting foundations.

I signed an NDA, so I can't give my questions.

REALLY know your Linux OS fundamentals, from high-level concepts (such as launching an executable) to low-level concepts (like the different implementations of virtual memory).

CareerCup and the Unix and Linux System Administration Handbook by Evi Nemeth were invaluable.
