After the CV, I was sent to do the online tests. These were fairly standard and no way you could prepare for it. Watch a video and answer questions relating to it. If you pass that, you have to do a quick 'culture interview' via Google Hangouts. Well its called a culture interview but I don't see how they were not your standard interview questions i.e. What made you choose Brainlabs? I didn't go any farther than there as I turned down the in person interview. Seems like a very relaxed and easygoing place to work, but I realised that I wanted somewhere more fast-paced.
