Grammarly Software Engineer Interview Guide

We've seen Grammarly evaluate software engineers less like a pure algorithm shop and more like a product-minded engineering team that wants to hear how you reason. Multiple candidates described interviews that mixed coding with open-ended discussion, and even the LeetCode-style prompts were often framed around explaining tradeoffs and complexity out loud rather than racing to a final answer. One candidate called out a rate limiter and another a graph deep copy on a whiteboard, which suggests the team still values fundamentals, but expects you to stay composed when the format is less polished than you might hope.

A recurring theme is that Grammarly cares a lot about whether you can connect technical decisions to real product impact. Candidates were repeatedly asked to walk through major projects, justify design choices, and discuss distributed systems or feature design for existing infrastructure. That tells us the strongest signal here is not just correctness, but whether your thinking feels practical and grounded. We also noticed that the interviewers were described as friendly and thoughtful, which usually means they are listening for clarity and structure more than memorized patterns.

One non-obvious factor that came up more than once was logistics. At least one candidate was surprised by how direct the team was about relocation and the meaning of “remote first,” so we’d treat location expectations as part of the evaluation, not a side note. In other words, Grammarly seems to reward candidates who are technically solid, can articulate impact, and are aligned with the company’s working model from the start.
