Interviewing naturally depends on which area you go into. R&D, Sales, Marketing, etc.
Interviews are basically generated from lazy HR folks who use "keyword" search for resumes that match "keywords" hiring managers used to describe the job position. So the trick is to be able to speak to the "keywords" during the interview.
The company does not have any standards for interviewing, it is a free for all and a potential employee could end up speaking to several mangers. Some of them will have a clue and KNOW how to interview and others will just ask you questions from your CV.
Best bet, try to interview with a European. They are actually clued into what's going on unlike managers in Boston or California.
