Cohere Senior Software Engineer mock interview
A live voice mock calibrated to this role — real questions, the real follow-up rhythm, and a score at the end. Free to start.
Two senior IC tracks sit under this title at Cohere: one builds the infrastructure that lets autonomous agents run safely (sandboxing, identity, routing, rate limits), the other builds the security-focused agents that run on top of it (alert triage, code review, threat modeling). Both expect production Python depth and comfort reasoning about security at multiple layers.
What this interview tests
- Secure execution and sandboxing — Running untrusted, agent-generated code safely is the core mandate of the Agent Infrastructure track.
- Identity and access design for non-human callers — Designing authentication and permission scoping for autonomous agents, a focus area named directly on the Agent Infrastructure posting.
- Agent orchestration at scale — Model routing across providers and rate-limiting or quota systems for many concurrent long-running agent workflows.
- Multi-layer security engineering — Reasoning about application, agent-behavior, and infrastructure-level security together, and defending against an agent being manipulated into unsafe tool use.
- Production judgment under ambiguity — Taking a research idea to production infrastructure with no existing playbook, or debugging and securing an unfamiliar codebase under time pressure.
- Production Python at scale — Both postings name strong production Python experience as a baseline requirement, not a nice-to-have.
Common question themes
Design a sandbox for executing untrusted, agent-generated code safely.

Design a rate-limiting or quota system for many concurrent, long-running agent workflows.
Named question theme for the Agent Infrastructure track.
Design an agent that safely triages security alerts with access to sensitive data.
Named question theme for the Security Agents track.
How would you defend against an agent being manipulated into unsafe tool use?
Named question theme for the Security Agents track.
Tell me about taking a research idea to production infrastructure with no existing playbook.
Named question theme for the Agent Infrastructure track.
Walk through a security feature you shipped end to end.
Named question theme for the Security Agents track.
Debug and secure an unfamiliar codebase under time pressure.
Named question theme for the Security Agents track.
Likely format
Neither posting names a format. Based on question style, expect system-design conversations centered on agent security and infrastructure tradeoffs, paired with behavioral questions about shipping under ambiguity, rather than generic algorithm-focused rounds.

Frequently asked questions
Is this a security role or an infrastructure role?
It depends on the posting. The Agent Infrastructure track is platform engineering — sandboxing, identity, routing, and rate limits for agents to run on. The Security Agents track builds the agents themselves for enterprise security use cases like alert triage and threat modeling.
Do I need prior AI agent experience?
Both postings expect real experience building autonomous or AI-agent systems specifically, not just general backend experience, alongside the security depth each track calls for.
What language should I be strongest in?
Both postings name production Python at scale as a core requirement, so expect that to be tested directly rather than treated as one option among several.
