Process
An employee referred me to the recruiter.
The first step was an online test to ensure I knew how to write code in my chosen language. It was fairly easy.
Next, I had a phone screen with a Square engineer. We solved a problem using a collaborative code editor for 45 minutes and discussed the company and its work environment for the remaining 15 minutes. This question was also fairly easy, and the engineer was cheerful and supportive.
They invited me to visit their office for a day of interviews, but unfortunately, I was unable to attend in person. Instead, we arranged for Square to visit my campus for a 1-hour interview.
Square claims on its engineering blog that the interview process is "pair programming" – this is an exaggeration at best. I implemented the code while explaining my reasoning, but the interviewer repeatedly interrupted me, saying "you don't have to say that" or "you don't have to tell me that." About halfway through, the interviewer began responding to emails and pull requests on their computer.
