Acing a job interview isn't about luck. It's about structured preparation — seven concrete actions that, done in the right order, take a candidate from “OK” to hired. Recruiters don't decide based on the whole interview: they decide on 5-7 micro-moments, and most candidates miss at least 3 of them.

This guide condenses the method used by Vocacia mentors — bankers, consultants, product managers, lawyers in current roles — into seven actionable steps. Each step takes 30 minutes to 2 hours of prep. Do all seven, and you'll land 2-3x more offers than candidates who only do half. For the full chronological timeline (3 weeks before, day-of, after), see our complete guide to preparing for a job interview.

TL;DR — the 7 steps in 60 seconds

1. Know the firm better than other candidates (60 minutes of targeted research).
2. Have a 90-second personal pitch (the 3-act story).
3. Prepare 5 STAR stories covering the classic behavioral questions.
4. Prepare 8 questions to ask (3 operational, 3 strategic, 2 human).
5. Read the recruiter's non-verbal language and adapt your pace.
6. Handle trick questions calmly (salary, weaknesses, why us).
7. Send the follow-up that converts (24h after, 4-line structure).

Step 1 — Know the firm better than other candidates

This step separates the “I read the About page” candidate from the “I understand the strategy” candidate. Most candidates do the first. The best do the second — and that changes everything.

The 4 sources that matter

• Your interviewer's LinkedIn (10 min): path, recent posts, mentioned projects. Look for 1-2 connection points (school, previous employer, common interest) for the first seconds of the interview.
• Press releases from the last 12 months (15 min): launched projects, acquisitions, fundraising, new markets. Identify 1-2 strategic elements you can mention.
• Glassdoor (15 min): culture seen by employees. Read detailed comments (not the overall rating).
• Podcasts or CEO interviews from the last 6 months (20 min): this is where you find the real strategic priorities of the year. Quote a precise sentence in the interview — immediate signal of seriousness.

Total: 60 minutes of targeted research that puts your application in the top 10% best prepared.

The casual conversation test

Before the interview, verify that you can answer casually these 4 questions without hesitation: (1) what's the firm's most recent project? (2) who are their 3 main competitors? (3) what was the latest acquisition / fundraise? (4) who is the CEO and what have they said publicly this quarter? If you stumble on any of these 4, go back to research.

Step 2 — Have a 90-second personal pitch

“Tell me about yourself” is the worst-prepared question. Average candidates tell their CV in 4 minutes. The best have a 3-act pitch that lasts 90 seconds max.

The 3-act structure

• Act 1 — Where I come from (15 seconds): main education + first career choice + the why.
• Act 2 — What I do now (40 seconds): current role + one concrete project with measured impact (numbers).
• Act 3 — Why I want this role at your firm (30 seconds): explicit link between your trajectory and the opening, with a reference to what you found in Step 1.

The trap: 90 seconds seem short. You'll be tempted to include everything. Resist. A well-built 90-second pitch beats a 4-minute pitch that covers everything by 10x.

Practical test

Record yourself on your phone. Re-listen. If you exceed 90 seconds, cut. If you hesitate at more than 3 spots, rewrite. If the last sentence doesn't explicitly point to the company, rework Act 3.

Step 3 — Prepare 5 STAR stories

Behavioral questions hit in every interview: “describe a situation where you handled conflict,” “tell me about a failure,” “describe a project you're proud of.” Prepare 5 stories that cover the most common angles.

The 5 stories to prepare

1. A leadership story — project where you led a team.
2. A failure story — project that didn't work and what you took from it.
3. A conflict resolution story — disagreement with a colleague or manager.
4. A fast learning story — you had to master something quickly.
5. A measurable impact story — project whose impact is quantified.

The STAR method in 90 seconds

• S — Situation (15 sec): precise context (project, team, stake).
• T — Task (15 sec): your role and the objective set.
• A — Action (45 sec): what YOU did. The most important part. Detail the decisions made.
• R — Result (15 sec): measurable impact (numbers if possible) + what you took away.

The STAR trap: 80% of candidates stay in “Situation” too long and reach Action in 30 seconds. Invert: compress context, expand action. Action is where your competence reveals itself.

Step 4 — Prepare 8 questions to ask

“Do you have any questions?” is where 90% of candidates fail. 1-2 lukewarm questions (“what's the work-life balance?”, “how does training work?”) signal you haven't thought about it. Prepare 8: 3 operational, 3 strategic, 2 human.

The 3 operational questions

• “Over the first 90 days, what are the three main outcomes you'd want to see from the person taking this role?”
• “How does the team work day-to-day — tools, rituals, frequency of team check-ins?”
• “What's the main difficulty the team is facing right now?”

The 3 strategic questions

• “You launched [project/product X] recently. How do you see it evolving over 12-18 months and where does this role fit in that vision?”
• “What success metrics do you personally track for this team?”
• “How does this team interact with [adjacent team you identified in research]?”

The 2 human questions

• “What made you join the team / company, and what did you find here that you hadn't anticipated?”
• “What's the profile of the person who's been most successful in this role over the last 2 years — what set them apart?”

These 8 questions, in this order, signal: (1) you think in outcomes, (2) you understand strategy, (3) you're interested in people, not just the title. Keep 3-4 in reserve for ones already answered during the interview.

Step 5 — Read the recruiter's non-verbal language

This step separates the “technically good” candidates from the “we want them on the team” candidates. It's subtle but not mystical — three concrete markers to watch and three adjustments to make.

The 3 signals to read on the recruiter

• The pace of their questions: if they chain without pause, they're in “quick screening” mode — answer concisely. If they ask open questions with pauses, they want a real conversation — expand.
• Their posture after your answers: if they take notes, they're interested in the detail. If they nod without noting, they validate the direction but want to move on. If they stay silent after your answer, they want you to elaborate (or they're testing your tolerance for silence).
• Eye contact: if they look at you most of the time, good signal. If they look at their screen/paper more than at you, reinject energy (a strong number, a precise anecdote).

The 3 adjustments to make

• Match your pace to the recruiter's. Faster if they chain, more measured if they take their time.
• Reformulate their questions before answering, especially if the question is ambiguous. “To make sure I understand, you're asking if X or rather Y?” — signal of structured thinking.
• Take deliberate 2-3 second pauses after each question. Short silence before the answer signals control. Most candidates chain because of stress — don't.

Step 6 — Handle trick questions calmly

Three questions hit in 70% of interviews and destabilize most candidates. Prepare them in advance — you'll avoid the panicky responses that cost the offer.

“What are your weaknesses?”

Worst answer: “I'm a perfectionist” or “I work too hard.” Everyone says that. The recruiter hears it ten times a day — it's become a negative signal.

Good answer: a real weakness + a compensation mechanism. Example: “I struggle to say no when I'm asked to take on projects adjacent to mine. Early on it cost me weeks of overload. Now I have a system: every Monday I list my priorities for the month, and when something new comes up, I say ‘yes if X drops off my list.’ It forces the trade-off conversation.”

What works: the weakness is credible, the mechanism shows maturity, the last sentence shows you can make trade-offs.

“Why our company?”

Worst answer: “Because you're an industry-leading company with a strong culture.” Generic, interchangeable, instant negative signal.

Good answer has three ingredients: (1) a reference to a recent event or project you read about in Step 1, (2) an explicit link with your trajectory, (3) an implicit question you want to explore in the role. Three elements, three sentences, done.

“What are your salary expectations?”

Strategy 1 — Turn the question around (recommended for juniors): “I'd like to understand the range you have in mind for this role, based on the experience required. I'm confident that if we're aligned on the role, we'll find an agreement on compensation.” 70% of recruiters share their range.

Strategy 2 — Give an anchored range (3+ years experience): “Based on the market and my current responsibilities, I'm targeting X to Y. I'm flexible if the overall package is attractive.” Give the market range + 10-15%, never more.

Step 7 — Send the follow-up that converts

90% of candidates send a “thanks for the time” 24h after. Better than nothing. The 10% that land offers send a follow-up that adds value — that's what makes the difference when the recruiter is hesitating between two similar profiles.

Structure of the winning follow-up (sent 24h after)

1. One personalized thank-you sentence (a specific detail from the conversation).
2. A reference to a topic discussed that struck you and that you've thought about since. Example: “You mentioned the challenge of X — I thought of an angle Y we didn't have time to explore.”
3. A value-add asset: an article you cite, a number, a similar case in another industry. Without showing off. 2-3 sentences max.
4. A closing sentence that reaffirms your interest and opens the door to next steps.

This follow-up takes 20 minutes to write and tips 1 in 5 decisions. To push further, add a LinkedIn connection 48h after the email — short message reminding the meeting context.

Recap — the 7 steps in practice

For an interview in 7 days, here's how to spread the 7 steps:

• D-7: Step 1 (company research, 60 min)
• D-6: Step 2 (personal pitch, 60 min writing + recording)
• D-5: Step 3 (5 STAR stories, 90 min)
• D-4: Step 4 (8 questions to ask, 30 min)
• D-3: Step 6 (prepare the 3 trick questions, 60 min)
• D-2: Mock-interview with a working mentor (60-90 min) — the step that creates the most value in the least time
• D-1: final recap + Step 5 (mental prep on non-verbal language)
• D+0: interview — apply Steps 5 and 6 live
• D+1: Step 7 (the follow-up that converts)

Total: 6-7 hours of prep spread over 7 days. Plus the mock-interview that multiplies the effect of everything else.
