The interview process includes two phone interviews, followed by an onsite interview at our San Francisco, CA office.

The recruiter team is good.

Technical interviews can be difficult, and the onsite interview will be the most important. Use common sense and Computer Science knowledge and skills to answer all questions.

Think of anything Linux; they may ask you random questions from all kinds of areas, like networks and programming.

And last but not least, an interview with the Director. I must say, this person seems to live on another planet.

Without an intro or basic greetings, they started writing a problem on the whiteboard and asked you to write an algorithm and then the code. While you explained what you were writing, they were answering emails and didn't even care to look at your solution.
