I applied through a recruiter. The process took 3 days. I interviewed at Refme (London, England) in June 2014
Interview
I did the interview in the early company stage, so maybe the interview process right now is slightly different. I was asked to do an iOS exercise about storing some date into a database and allowing the user to delete date from a list. After passing the first interview phase I was asked to do an in-site phase where I had to answer to few technical question mostly about iOS.
