Phone call, followed by technical challenge. Tech challenge with 3 people. Had to discuss a problem with them. Found the whole process doable but no offer. People were very nice.

Applied directly from their site. After a week or so, I was contacted by phone and then they sent me a simple programming challenge. After another week or so, an on-site interview was schedule, with both HR and some middle manager guy. The interview followed the classical format: talk about me, about the challenge and about the position. After another week, another interview. This time with a couple of middle managers, to talk again the talk about me and about the position. The next step would be another interview. After a few weeks, no more interviews - my application was discontinued. Advice for future applicants: unless your nature is right, don't burn daylight.
