I applied through a recruiter. The process took 1 week. I interviewed at Block in Jul 2015
Interview
Was very nervous at first about what I would be asked seeing as I hadn't interviewed in the past 3 years. I applied through a recruiter that then helped me schedule a Skype call with an engineer at square. I was afraid of the question I would be asked because I have read that the interview was very difficult. When presented with the question I was surprised because I was capable of solving it. There was a 45 min time limit and you were allotted 15 min at the end for questions. I was capable of solving the question but I took too long doing so and for this reason I failed. By the way I am a decent programmer and I think the question asked was very fair. Just make sure you do many practice problems so that you are quick on your toes when coding the solution.
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.
