AI-Powered Interview Preparation
The prep tool built
for delivery leaders.

Every interview prep tool on the market is built for engineers. Vantage is built for the roles they all ignore — programme managers, delivery leads, operations and resource managers. Paste a JD, get questions calibrated to your seniority, and walk in knowing exactly how to frame your experience.

The Problem

Nobody built this for us.

Final Round AI, Yoodli, Big Interview, LinkedIn's prep tools — all of them assume a software engineering candidate. STAR coaching that ignores seniority. Questions that test coding ability, not delivery judgement. A Director and a Coordinator get the same generic feedback. For PM, programme, delivery and resource-management roles — the most common roles in a 40-person consultancy — there's nothing.

◇ What exists
Generic STAR templates. Engineering-flavoured questions. One-size-fits-all feedback regardless of whether you're a coordinator or a VP.
✦ What Vantage does
Reads your actual JD, generates delivery-vocabulary questions calibrated to your target seniority, and tells you — in your own words — exactly where your framing is too tactical.

Nine Integrated Modules

Built as one system — not nine tools.

Every module feeds the next. Company intel sharpens your evaluation. Your evaluation history shapes the next session's feedback. Real interview debriefs feed the same pattern engine as practice sessions.

01 · Core Engine
Seniority-Calibrated Questions
6 questions per JD — 3 behavioural, 2 situational, 1 curveball — each mapped to a competency the JD actually signals. A Director gets organisational-impact framing; a Coordinator gets execution framing.
02 · Memory
Session Context Threading
Each evaluation sees your last two answers. If you reuse a story, or repeat the same tactical-framing mistake, Vantage names the pattern — not just the single answer.
03 · Activation
Warmup Mode
The morning of the interview — pulls your 3–5 strongest saved answers, 90-second read timer per answer, then a single reflection prompt. No scoring. Pure activation.
04 · Live Coaching
STAR Coach
As you type, four tip cards track Situation → Task → Action → Result in real time, with a quiet contextual nudge for whichever stage is missing. Zero AI calls — pure client-side pattern detection.
Differentiator
05 · Personas
Hiring Manager Personas
The same answer, reframed four ways — for a Hiring Manager, an HR screener, a peer Delivery Leader, or a client-side Executive. Same facts, different emphasis, because interviews aren't one audience.
Differentiator
06 · Post-Mortem
Post-Interview Debrief
After the real interview — paste what you were actually asked, rate how each went. Vantage reads between the lines: what was really being tested, what's a genuine gap, what to fix before round two.
Differentiator
07 · Long-Term Memory
Cross-Session Pattern Coaching
After 3+ sessions — including real-interview debriefs — Vantage surfaces what's consistent: "Impact is always your lowest score — you describe what you did but rarely land what changed." A coach that remembers.
Differentiator
08 · Company Intelligence
Four-Layer Company Brief — Not a Wikipedia Summary
Live search signals (funding, leadership, restructuring) + JD-language decoding + sector-stage reasoning, synthesised into: what this company is dealing with right now, what they're likely screening for, what to weave into your answers — and which of YOUR prepared stories fits best. The brief feeds directly back into your evaluation feedback.
Also Included

Questions you ask — flip the signal.

The questions you ask the interviewer say as much about your level as the answers you give. Vantage generates JD-derived questions grouped by audience — Hiring Manager, HR, future peers — each with the signal it sends and what a good vs red-flag answer sounds like. Plus three questions to explicitly avoid, and why.
