Squarespace Front End Interview Questions
Find more company guides on GreatFrontEnd.
Squarespace's front-end loop has recently moved away from a take-home and toward a live debug-style tech screen. They are reportedly very transparent about what each round contains — confirm with your recruiter.
User interface coding questions
- Tech screen: vanilla JavaScript bug-fix. You are given a working but buggy file with several classes (the example reported was a shopping cart with review comments and a 5-star rating widget). One by one the interviewer tells you what the bug is (e.g. "the 5-star widget lets you review more than once") and you fix it. Bugs cover state manipulation, array handling, DOM updates. Open book — you can search online. At the end, they ask for an overall code review of the file: how you would have implemented the whole thing differently, what you'd change about data, state, and performance.
- The buggy classes-based shopping cart also contains a star-rating widget — practice the basic Star Rating component before going in.
- Practice question (Free)
System design questions
- Implement / design a Kanban board (onsite system design round).

Squarespace FE tech screen update — they've changed the format, so older threads / Glassdoor posts about take-homes may not match anymore. The interview is in vanilla JS. They give you a buggy JS file with a bunch of classes (mine was a shopping cart with review comments and a 5-star widget). One by one, they tell you what the bug is (e.g. "the 5-star widget lets you review more than once") and you fix it. Some fixes are about manipulating state and arrays.
It's open-book — you can search online. The interviewer tries to guide you toward the right path, very friendly. At the end they ask for an overall code review: how you would have implemented the whole thing differently. They're looking for tips on improving data/state, performance, etc.
Heads-up: the classes have intentionally generic names which makes it harder to track what does what.

The recruiter told me the system design round (onsite) at Squarespace will be implementing a Kanban board. Good to know what to prep ahead of time.
