I was approached by a recruiter through LinkedIn. Square has a very standard tech interview process.

First, I spoke with the recruiter on a short call, discussing my past experiences and so on.

Next was a technical phone screen with an engineer, featuring a simple programming question.

After that, I received an invitation to come onsite for a full-day interview. This consisted of:

• Three pair programming exercises
• Lunch
• A design session
• A one-on-one with a manager

My partners for the pair programming exercises were great and were more than willing to help and answer my questions. Overall, it was a great experience.

All interviewers come up with their own questions, so it is hard to generalize a set of questions.

For my set, the questions were centered around recursion.
