Process
The interview process consisted of an intro call with a recruiter, a tech screen (pair programming), and an onsite interview. The onsite included:
- Three pair programming sessions
- A systems design session
- A past experience discussion
The pair programming questions were not LeetCode questions but progression-based and were actually quite fun to work through. I didn't ace all the questions; for some, it was enough to complete the majority of the parts and discuss the final part within the approximately 50-minute time limit.
Problems were at most equivalent to medium LeetCode questions. The onsite can be exhausting with three 50-minute pair programming sessions back to back, on top of the other sessions, and only a single short break.

Block Work Experiences
- 4.0Remote Work, Limited GrowthSoftware Engineer • Current EmployeeVancouver, British Columbia, CanadaOctober 24, 2025Pros: - Good work-life balance - Good benefits - Remote workCons: - Scope is limited - Limited growth space
- 5.0Fun, challenging, and rewardingSoftware Engineer • Current EmployeeMay 10, 2014Pros: It's great getting to work with a very talented team. I love learning something new and getting challenged each and every day. The company is incredibly transparent internally, which is really refreshing. I love building products that empower local merchants. Compared to big tech companies that I've worked at, I feel like Square is a great place where we can win as a team.Cons: Growing fast and having many offices around the world has come with challenges. The amount of internal communication can be mind-boggling if you don't quickly figure out a system for managing it. If you are the kind of person that needs to know exactly what you'll be working on in two months, then Square isn't for you.
- 5.0Definitely has its faults but overall, would do again.Software Engineer • Former EmployeeMarch 17, 2026Pros: It has a very open culture, and for the five years that I was there, I really enjoyed the work I did for the most part. Even though I got laid off, I do think the company's direction in terms of really leaning in on AI and focusing more on its core product offerings is the right approach.Cons: There was a lot of company BS, and leadership would constantly change direction. There was a huge obsession with afterpay and crypto that did not pan out.
