Process
The interview process consisted of two technical phone screens, followed by an onsite with two pair-programming style interviews.
The interviewers were quite nice, and I also didn't have too much trouble with the questions.
I produced working code for all but one of the four questions, though I wasn't expected to produce working code for the last one.
My recruiter was very responsive, and the process went very smoothly.
