I applied through a recruiter. I interviewed at Groupon (Berlin) in Nov 2012
Interview
I applied through german recruiting agency.
After two interviews via skype (not very difficult) they invited me to their office in Berlin (they covered all the expenditures - flight and the hotel).
There were 3 interviews:
1. interview with HR about salary and organization
2. technical interview about java - usual technical questions + they asked me to write program on the whiteboard
3. architecture-related interview. They asked me to design the high-load system and describe how I would implement it.
