No phone interview, on-site interview arranged shortly after application. Three sections, of which two technical. The two technical sections were whiteboard-based and covered issues of signal analysis (identifying features in a trace, noise removal) and simple algorithm questions, respectively. Third section was HR based. Personally found this section trickiest with a very skeptical/agressive line taken by the lead interviewer (probably intentionally, in retrospect). Third section covered classic questions like "Why do you want this job?" and "Where do you see yourself in five years' time?"
