Applied online. Went through a quick phone interview with HR, invited to the office to carry out a technical interview. Interviewers were very relaxed, positive and encouraging - asked me high-level tech questions. I chose to use the whiteboard so that I could draw out my solution. Interviewers also took me on a tour of the office, which I thought was a nice touch. I'd recommend applying, great company.

Email asking me about my interests, asking me to describe previous projects and so on. Phone Interview asking me basic software engineering questions. On-Site interview, whiteboard tests, logic puzzles. I then had a tour of the office by one of the interviewers, all around, a pleasant experience.
