Their interview practises aren’t that different from other top tech companies, however they don’t have n+1 rounds of interviews, only one 1-1.5 hours long one, with 30 minutes of technical interview. Like other top tech companies they don’t look for coders, but creative, smart software engineers with a software architectural vein. According to the speaker in the technical part they give you a 1 page long code piece, which you have to read, understand, explain, and criticise. If you know what you are talking about, and they get the impression that you could work together, they will hire you.

Archicad has 17 MILLION lines of ( mostly ) C++ code.
