I applied through a recruiter. The process took 2 weeks. I interviewed at Block (San Francisco, CA) in Sept 2017
Interview
Recruiter reached out and had phone screen and onsite after that. Onsite interview had 7-8 interviews and you have to write code in real computer. There is a separate open section for interviews so place is bit noisy. Questions were not hard and some answers I gave interviewer couldn't understand. So it was a red flag.
Note: If you are good and you think you can crack interview of a bigger company don't waste too much time on Square because their compensation is very low and they don't change it. And I didn't feel there's lot of smart people and most of engineers are average. Specially if you are joining Caviar team they have low priority towards Caviar hiring so they don't increase or match counter offers. So Just do your interview to practice and let it go. My offer was 50k lower than others.
Inital take home, followed by extension interview, followed by a coding challenge, followed by system design interview.
The whole process took 3 months!
The interviewers are usually really nice and want you to do your best.
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
Phone screen and then a full day of interviews. 3 pair programming challenges, a system design review and a prior experience interview. There was also an onsite lunch with a person from the company.
