I applied through a recruiter. I interviewed at 11:FS (London, England)
Interview
Good HR/Recruiter interview (they knew what they were talking about!), followed by 3 technical rounds. Each round was harder than the last, including whiteboarding and pair programming. Enjoyable process, met lots of good people.
