First I was given an online IQ assessment, then a telephone interview, after that, they gave me a mock research project and asked me to finish it within 4 days. Finally, skype with the team.

Met a representative at a university career fair, basic first round interview, interesting written assessment that gives you a great insight into the work you would be doing. Overall a great experience and the people I met seemed like the best you could hope to work with. Couldn't proceed with the process because I needed to accept elsewhere, but would recommend to anyone.
