Entrevista
Pretty standard. First phone screen with recruiter. Second phone screen with an engineer. Then whole day onsite from 9am to 5pm. Free lunch in the company.
Pros:
1. They moved very fast.
2. The programming questions were pretty fun to work on. Use IDE, not whiteboard. Great.
3. The lunch was good.
4. The hand crafted coffee was awesome!
5. The office was nice.
Cons:
1. I didn't feel the excitement about the company from the recruiters.
2. The onsite was too long: 10am to 5pm. They were mostly coding questions. Though they were fun, I was very tired at the end of the day. I think three 1-hour long coding sessions should be enough for evaluating one's code skills.

Most difficult: A question that I solved with dynamic programming. I got it anyway.
Unexpected question: Describe what happen when someone requests a web page from browser. Man, this question is too common. I was asked many times in other places. I expected Square is more creative.

I had a call with their recruiter first, talked about my past experience and what I'm look in for in my next role. Then had a technical front-end screening with two engineers where I needed to build an application. I thought I did well, I was able to implement a working app, but I did not pass. Not further feedback was given.

Implement a memory game in any JS framework or vanilla JS. You need to implement this game based on some demo app that you can play around with before hand. You need to implement the HTML/CSS and JS all from scratch. The game has the following behavior: you need to display N x N cards in a grid lay out. The number of N should be configurable by the user through a slider. When the user clicks a "start" button, N cards a highlighted for 2-3 seconds. Then the user needs to click on the cards that were highlighted. If the user clicks on the correct card, it changes the color to green, otherwise it changes to red. If all the initially highlighted cards are clicked the game is over. What to watch out for: you need to track the cards that were clicked in the grid, you need pick N random cards to be highlighted for each round of the game. You need to make sure the gird of N cards can be increased and reduced. It's not enough that the app works, you also need to write clean/readable code. You have about 40 minutes to implement this, and you need to talk through your work.
Long process. System design felt like I aced it but they didn't pass me. It was the classic design a hotel booking platform question. They put you through a lot of rounds up front.
