They first conducted a phone interview after I applied online. They gave me a coding interview with one of their engineers. She was very professional and was a great interviewer. At the onsite interview, I discovered that the expectations were very different from the job description. People were very nice and asked standard questions.

contracted by a recuiter, first a 15 min phone screening, 1 week later, technical interview. 30 min discussion of research projects, you need to know very well the stuff you put on you cv, even you did it long time ago 30 min coding
