Process
This was a pretty standard interview. The initial 30-minute phone screen was with a recruiter, followed by an in-person interview with the hiring manager. Then, there were two separate panel interviews scheduled on different days, likely to spread out the interviews so I wasn't there for six hours straight.
The people were really great, and the product is good, but I live in the South Bay and just couldn't get over the commute, so I declined the offer after thinking about it.
Questions
Standard data structures and algorithms questions.
Some optimization questions.
Overall, pretty challenging but straightforward.

Square is a fantastic company with an aggressive roadmap for growth

Pros: The products are world-class, the brand is well-known, design is a first-class citizen, and there is a lot of room for growth both as a company and an individual.
Cons: I think we're really going through growing pains right now. There have been so many people added to the company in a short period of time that there is a lot of chaos and sometimes overlapping efforts from team to team.
Leadership has definitely identified this and is doing a good job aligning efforts at a global level.

Pros: The environment is very professional and can be serious (we are dealing with people's money, information, and well-being).
At the same time, everyone does a great job of making it fun and enjoyable. I think this is a tough balance to strike, but Square does it well.
The engineers work very hard and are protective of the quality of work and coworkers.
The discussions (on the record and off) are very insightful about everything from payments, engineering, and life.
Company meetings and transparency are informative and motivating.
Cons: The size of the company can be daunting. There are a lot of people, and Square is growing.
There are and have been some growing pains caused from scaling a startup into a large company.
