Block Software Engineer interview questions

Applied online had one telephonic code pairing round then onsite(virtual). 3 code pairing round 1 system design 1 past experience and the last one was with the hiring manager. A week later got a call from the recruiter and she told that "there was nothing major negative feedback from the team but you were not quite there". I have given so many interviews and almost always I know if I did well or not. This time I expected an offer considering my performance but it went another way. In retrospective what did I do wrong: I first code pairing I did 3 parts of the question, first was big other two were small. In the second & third code pairing, I did only one round and then I was out of time. In all three code pairing and in each part of the coding they had their own test cases all of them passed. So, logic was not the problem, then what was it? I selected Golang as my language and its little verbose than C# LINQ & Java lambda, which took some of my time. So, I think in order to clear the coding round one must do at least 3 parts. Even though you have the liberty to google for syntax or anything but that eats up your precious time. After spending 7hr in the process I feel like I shouldn't have applied for the position. It definitely hurts my confidence.

Pair programming rounds, system design, past projects deep dive. Square has the best interview process - hands down! The interviewers were kind, professional and competent. They will work with you to arrive at a solution. Strongly recommend.
