I applied through a recruiter. I interviewed at ASSIA (Redwood City, CA) in Jul 2017
Interview
A recruiter reached out to me to schedule an onsite interview. I had an interview onsite and I met the hiring manager and another manager. The interview was smooth, and easy. I thought that I did great. The recruiter asked me if I was in process with other companies; I said yes. However, recruiter insist that I should respond by the next day if I can start by next Monday. Also, she said that I should hear from her by the end of the week. I emailed her right after I got home that I am really interested and I will be available to start by next Monday. I thought I am going to receive an actual offer, so I cancelled an interview I had on that week. However, I did not hear back from them at all. I emailed the recruiter twice as a follow up and left a voice mail. I have not heard anything from them. To wrap up, I don't think that anyone should work for this company who does not value peoples' time. I spent time, money and energy, and I think I deserved a respond back even if it is a rejection.
I applied through other source. I interviewed at ASSIA in Apr 2014

The process was clearly defined since the beginning. It consisted on 4 interviews plus an initial call. One was on the phone and three on site. One of the interviewers forgot an appointment. Another focused excessively on statistical functions for the position.

I applied online. The process took 2 months. I interviewed at ASSIA (Madrid) in Mar 2014
Interview
3 interview stages. Personal questions, Technical questions (Linux & SQL) and Language evaluation (english). The personal description is via telephone, the other two phases 1:1 with similar level engineers. The conversation level is informal and the recruiters are pretty open to help you. You do not need a perfect score to pass.
