I applied through other source. The process took 2 weeks. I interviewed at Block (San Francisco, CA) in Feb 2016
Interview
Absolutely excellent. Taxing, but fair.
Step one: Phone screen with a recruiter.
Step two: In-person coding test, using pair programming, and your language of choice. Seriously - no bad marks for picking your favourite stack even if it isn't Ruby or Java.
Step three: Two more in-person pair coding tests, and about 5 hours of conversations.
Incredibly friendly, respectful, and pragmatic throughout the entire process.
