Grammarly leans on strings, tries and dynamic programming — a natural fit for text processing — plus a design round on low-latency suggestion serving.
Across the 30 questions on this page, the weight sits on these patterns:
This sheet collects 30 Grammarly interview questions, grouped into 16 patterns. They are questions reported as actually asked in Grammarly interviews, and each one carries how recently it was reported so you can practise the current set first.
Dynamic Programming, Binary Search, Stack come first — the patterns on this page are ordered by how often Grammarly leans on them, so working top-down spends your time where the interview actually is. The full order is Dynamic Programming, Binary Search, Stack, Design, Breadth-First Search, Depth-First Search.
At roughly 25 minutes per problem — reading it, solving it and writing the approach down — 30 problems is about 13 hours, or 1 weeks at ten hours a week. Most people do not need all of it: the first two or three patterns cover the majority of what gets asked.
