Grammarly Interview Guide
~25% easy, 60% medium, 15% hard · 8 tracked problems · Strings, Trees, Dynamic Programming
Overview
Grammarly interviews reflect their NLP roots. Trie problems, string manipulation, and word-break variants appear more frequently here than at other companies — directly relevant to the text processing that powers their writing assistant. For ML roles, expect NLP-specific questions about language models, text classification, and correction algorithms. For SWE roles, the process is standard with a string/text-processing flavor.
