I applied online. The process took 4 weeks. I interviewed at Block (San Francisco, CA) in Sep 2018
Interview
I applied online and then was contacted by a recruiter. I had one technical phone screening with an engineer then went onsite for an all day session of interviews. The onsite was 3 pair programming questions choosing a language of your choice and one systems design question (open ended) and lunch. Lastly a manager chat which was "ungraded" at the end of the day. The systems design question was given upfront so you had time to think about your solution. The interviewers wanted you to succeed, so the experience was very pleasant.
Thanks for this great summary of your interview process. We're happy to hear the interview experience was pleasant; hopefully you will keep Square in mind for the future!

The interviewer was nice, and he is friendly and willing to give hint, the question has 2 follow-ups, it was hard to complete in time. The question was not a typical LeetCode
