I applied online.
I had a phone interview a couple of weeks later that lasted about 45-60 minutes. It consisted of one technical question, but most of the focus was on the discussion of the position and company background.
A week or so later, I was asked to come in onsite and do another round of interviews. I met with about five individuals.
There were only a few simple whiteboard questions and some technical trivia about operating systems and concurrency. Everything else was behavioral.
The last interview was an informal talk between myself and a few other employees in order to get to know more about the job and company.
Whiteboard questions were almost identical to most interview study materials out there. Nothing too tricky.
