I applied online. The process took 3 weeks. I interviewed at University of Cambridge (Cambridge, East of England, England) in Jan 2012
Interview
The process was good - they asked standard questions for my area of study. I did the interview over skype as I was in a different country at the time. They were quite understanding though. I was also applying to other universities at the same time. Overall the process was quite streamlined.
