Cohere Interview Guide
8% hard, 75% medium, 17% easy · 12 tracked problems · Arrays, Strings, Sliding Window
Overview
Cohere interviews focus on real-world LLM engineering. Instead of abstract algorithm puzzles, you'll tackle problems like top-k token decoding, deduplication in embedding spaces, and building efficient inference pipelines. If you understand how language models actually work under the hood, you'll have a significant edge. The difficulty is moderate — 75% medium — with an emphasis on practical implementation skills over theoretical optimization. Cohere wants engineers who can build production LLM systems, not just solve LeetCode. As a smaller AI company, the culture is more startup-like. Expect fewer rounds and faster decisions than at Google or Meta.

Interview Process
| Round | Type | Duration | Description |
|---|---|---|---|
| Technical Screen | Coding | 60 min | Practical coding, often LLM-related |
| Onsite (3-4 rounds) | Mixed | 60 min | Coding, system design, and LLM domain knowledge |
Technical screen, then 3-4 onsite rounds mixing coding, system design, and LLM-domain questions. Timeline is 2-4 weeks.
Difficulty Breakdown
75% medium, 17% easy, 8% hard is approachable. The challenge is domain specificity — knowing LLM internals matters more than grinding hard algorithm problems.
