Process
I had a very positive interview process overall.
My recruiter was exceptionally helpful every step of the way and provided detailed feedback after each round, which really helped me prepare.
There was a lot of effort put into tailoring the interview experience such that I was speaking with members of the team I was interviewing for directly. Everybody was warm, engaged, and helpful.
The interview process consisted of three rounds:
- Recruiter screen
- Hiring manager screen + technical screen (vanilla JS related questions)
- Onsite with four rounds (2 pair programming, 1 system design, 1 project deep dive)
Pair programming rounds all involved vanilla JS or HTML/CSS, which was directly relevant to the role. They were all pretty fun, puzzle-like questions that were very unique and interesting to work through.
Questions
Hotel booking system design:
Create DOM elements using vanilla JS.

Block Work Experiences
- 5.0Square is a fantastic company with an aggressive roadmap for growthFrontend Engineer • Current EmployeeSan Francisco, California, United StatesOctober 14, 2014Pros: 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.
- 5.0Fun and ProfessionalFrontend Engineer • Current EmployeeSan Francisco, California, United StatesOctober 14, 2014Pros: 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.
