Squarespace coding interview
questions, leaked.
3 problems reported across recent Squarespace interviews. Top patterns: array, two pointers, sorting. The list below is what most reported candidates actually saw, plus the honest play if you can't grind all of it.
Squarespace's coding assessment is small but sharp. Three problems across easy and medium, and they're testing whether you can build real systems, not just solve algorithmic puzzles. You're looking at array merging, cache design, and string validation. The mix is deceptive: two easy problems can lull you into complacency, then LRU Cache hits and you need to thread a doubly-linked list through a hash table under pressure. This is where StealthCoder becomes your safety net. If you blank on the design pattern mid-assessment, it surfaces a working solution in seconds, invisible to the proctor.

The topic distribution here is horizontal, not deep. Squarespace isn't drilling you on one pattern. They're testing breadth: can you handle arrays, strings, hashing, linked lists, and system design all in one sitting. Two easy problems mean you can't skip prep, but they also mean most candidates will start confident. The LRU Cache is the real test. It's medium difficulty, requires you to know doubly-linked lists cold, and combines hash-table lookups with linked-list pointer manipulation. That's where people choke. The easy problems (Merge Sorted Array, Valid Parentheses) are your warm-up. Get those right fast, then spend your mental energy on LRU. If you hit a wall on the cache design, StealthCoder's real-time solve is your hedge for whatever you didn't drill in time.

Squarespace interview FAQ
How much time should I spend on array and string problems for Squarespace?+
Don't overinvest. Two of the three problems are easy (Merge Sorted Array, Valid Parentheses), so one afternoon of focused drilling on two-pointer merging and stack-based parenthesis matching gets you there. Save your energy for LRU Cache, which requires deeper understanding of data-structure design.
Is LRU Cache really necessary to study before this interview?+
Yes. It's one of three problems and it's the only medium-difficulty one. It combines hash tables, doubly-linked lists, and design thinking all at once. You need to know the pattern cold: O(1) get and put operations, eviction logic, pointer updates. This is where most candidates drop points.
What order should I prep these topics in?+
Start with Valid Parentheses and Merge Sorted Array. Both are easy and can be solved in under 10 minutes each with solid understanding. Then move to LRU Cache. It's one problem but it's dense. Understand how to link a doubly-linked list to a hash table for O(1) lookups and eviction.
Do I need to know design patterns for Squarespace?+
Yes. LRU Cache is explicitly a design problem. You're not just implementing a function; you're architecting a data structure that balances multiple constraints (constant-time access, constant-time eviction). Expect the interviewer to ask you to justify your design choices.
Is two days enough prep for this assessment?+
If you already know hash tables and linked lists well, yes. Two easy problems take a few hours. LRU Cache needs a day of focused study: understand the pattern, code it from scratch twice, trace through eviction scenarios. If you're weak on pointers or hashing, add another day.
