# interview-agents Five AI agents that run your technical interview prep: three mock interviewers and two coaches. They run realistic, staff-bar sessions and give you brutally honest feedback. They run as [Claude Code](https://www.claude.com/product/claude-code) subagents, on your machine, for free. I built these to prepare for my own interviews. They replaced a paid interview-prep subscription for me, so I am sharing them. They work for any individual contributor at any level: you tell them your background once, and they calibrate to the bar you are targeting. ## See it in action A slice of a coding round. The agent stays in character while it interviews you: > **Interviewer:** You reached for a hash map. Before you write it, give me the worst case. > **You:** Lookups are O(1), so O(n) overall. > **Interviewer:** Average case. I asked for worst case. What happens to a hash map under adversarial keys? > **You:** ...collisions degrade it to O(n) per lookup. So O(n²). > **Interviewer:** Right. Keep going. Then time runs out and it drops the persona for the verdict: > **Verdict: leaning hire, not strong.** You found the optimal approach, but I had to pull the complexity analysis out of you twice (04:10, 11:35). At a senior bar you state worst case unprompted. >
