Human interview coaches are effective but expensive — usually $100–$250 per hour. Most job seekers can't afford 8 sessions before an onsite. An AI interview coach gives you the same rubric feedback ("your answer had no result," "you're 3 minutes long"), unlimited reps, and side-by-side rewrites at a fraction of the cost — free on the written tier.
What the coach scores
- STAR structure. Situation, Task, Action, Result — each present or missing.
- Specificity. Did you name systems, teams, metrics? Or generic "the team"?
- Result strength. Was the outcome quantified? "Cut latency 180ms P95" vs "improved performance."
- Length. 45–90 seconds is the target zone.
- Filler density. "Um," "like," "kind of," "basically."
- Verb variety. Same verb starting every sentence is a tell.
How coaching sessions work
- Pick a question set (behavioural, technical, or role-specific).
- Answer question 1 out loud or in writing.
- See a rubric score, a rewrite, and the top-two things to fix.
- Redo the same question with the fix applied.
- Move on when your score crosses 8/10.
AI coach vs human coach
| Dimension | AI coach | Human coach |
|---|---|---|
| Cost | Free / low-cost | $100–$250/hr |
| Reps | Unlimited | Session-limited |
| Rubric feedback | Instant, consistent | Instant, subjective |
| Narrative pivots | Good with prompts | Better |
| Confidence coaching | Indirect | Direct |
| Best use | Volume of reps | 2–3 high-stakes rounds |
Combine both for high-stakes interviews
For executive rounds or panels, the ideal is 2 hours with a human coach to build the narrative, then 10 hours with the AI coach to drill the reps. Details at interview prep coaching vs AI.
