I applied online. I interviewed at Block in June 2019
Interview
The recruiter I initially talked to over the phone was great, interested in my career goals, and was engaging. The technical phone screen was entirely opposite. The interviewer was completely disinterested from the beginning, didn't understand the programming question, and reluctantly answers questions about company culture. This reflected poorly on Square as a place to work and the quality of engineers there.
Interview questions [1]
Question 1
Given a a n x n array, find shortest path from (0, 0) to (n, n) and you can only move left or down.
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.
