I applied online. The process took 1+ week. I interviewed at Future Platforms (London, England) in Oct 2013
Interview
Applied through website and was invited to telephone interview. This consisted of an introduction to the company, a more detailed discussion of my CV, a short technical test using a shared document to write on and then the opportunity to ask questions.
Was invited in for face-to-face interview with two people that involved a bit more discussion of my background and then some harder technical questions and general technical discussion. I also got the opportunity to show of some of my previous work.
Interview questions [1]
Question 1
The technical questions in the telephone interview weren't specific to my background, but were more general programming exercises. The main interview was harder with some questions specifically about iOS programming. I felt all the questions were fair though - there aren't any gotchas on anything like that.
