TL;DR. 63% of hiring managers flag dishonesty as the #1 interview red flag, and 62% penalize candidates who badmouth a previous employer (HBR 2024). Preparation is exactly what lets you hold a credible, bullshit-free narrative. This checklist gives you 47 items across 5 milestones (D-7 to D+2): company research, STAR in 2 minutes, mock, reverse questions, logistics.
Your interview is in 7 days. You're telling yourself "I've got time". Wrong.
Most candidates lose offers on avoidable stuff: no questions at the end, fuzzy stories, late arrival, embarrassing video background — and per HBR 2024, a narrative that smells of embellishment or a slip-up about a former employer.
The gap between "we'll be in touch" and "when can you start?" sits inside a checklist. Here's the one we run with hundreds of Velyq candidates.
Would you rather wing it and hope, or execute a plan?
D-7: systematic company research (12 items)
The first filter the recruiter runs is simple: "did they do their homework?". They feel it within 3 minutes.
According to the HBR Guide to Standing Out in an Interview (2024), a candidate who hasn't dug into the business model, competitors and recent press gives themselves away during the very first round of questions. The good news: this is the easiest part to lock down.
Map the company (4 items):
- Business model in 1 clear sentence (who pays, for what).
- 3 latest key results (revenue, funding round, restructuring, product launch).
- 2-3 direct competitors and their differentiation.
- Press coverage over the last 90 days (Google News + "past month" filter).
Identify the interviewers (4 items):
- HR recruiter's LinkedIn (career path, recent posts).
- Future manager / N+1 (publications, projects cited).
- A "neutral" employee at the same level to calibrate the culture.
- Shared connections (a short DM to a former colleague can unlock everything).
Dissect the job description (4 items):
- 5 key competencies explicitly required.
- 2-3 ambiguities to clarify in the interview (scope, team, budget).
- House jargon to reinject naturally.
- Role context (new hire, replacement, growth?).
For public-sector processes, France Travail (the French unemployment agency) describes the standard structure: CV/cover-letter screening, HR interview, hiring manager interview. Adapt your research depth to the stage you're about to face.
D-3: prep your STAR stories (10 items)
STAR = Situation, Task, Action, Result. It's the universal grid for behavioral questions — and per HBR on the STAR method (2025), the expected standard for any structured recruiter in 2026.
Golden rule: 2 minutes max per answer (HBR 2025). Past that, the interviewer drifts. What feels short in rehearsal is more than enough on the day.
List your experiences (3 items):
- 8 to 10 flagship stories from the last 3 years.
- For each: 1 win, 1 recovered failure, 1 conflict handled.
- Tag by competency (leadership, deadline, technical, client).
Structure each story (4 items):
- Situation: 2 sentences of context (company, team, stakes).
- Task: your exact mission (don't conflate it with the team's).
- Action: what you did (action verbs, "I", not "we").
- Result: quantified. %, $, deadline, user count. No number = no story.
Adapt to the context (3 items):
- Amazon or Big Tech: map each story onto a named Leadership Principle (HN discussion).
- SMB: emphasize team impact and resourcefulness with limited means.
- Scale-up: velocity, experimentation, ability to pivot fast.
D-1: mock interview, logistics, outfit (11 items)
This is the milestone most candidates sabotage. Not from negligence — from overconfidence.
Mock interview (3 items):
- 2 sessions minimum, out loud (writing it down doesn't count).
- With a friend, a coach, or a training AI.
- Record yourself once. You'll hate it. That's the point: your brain corrects what it hears.
On Hacker News, the senior dev consensus is clear: rehearsing out loud massively reduces trap-question and technical-block mistakes.
Test the video setup (4 items):
- Camera at eye level (book under the laptop if needed).
- Mic tested on a 30-second recording.
- Neutral background, light facing you (not back-lit by a window).
- Meeting link verified, app installed, backup browser ready.
On-site logistics (2 items):
- Commute tested with a +20 min buffer.
- 3 printed CVs, notebook, pen that actually works.
Outfit and sleep (2 items):
- Neutral outfit, clean, pressed — no visible competitor logo.
- Lights out before 11pm, no screens 1 hour before. Mental prep matters as much as technical prep.
D-Day: the 9 items during the interview
You've done the work. All that's left is to execute without self-sabotage.
Before walking in (2 items):
- Arrive 10 min early. No more (you put pressure on the recruiter), no less.
- Smile at the front-desk staff. They're often debriefed afterwards — a cold candidate at reception travels back upstairs.
The first 60 seconds (2 items):
- Firm handshake, 3-second eye contact, "thanks for taking the time".
- Per HBR on connection in interviews (2024), the first 90 seconds carry disproportionate weight in the evaluation.
During the exchange (2 items):
- Rephrase every question before answering. Simple technique that slashes off-topic answers on trap questions.
- Demonstrate the 5 human traits that HBR 2025 "Are You Interviewing a Candidate or Their AI" identifies: social reading, live reasoning, quality of your questions, agility, collaboration mindset. That's what ChatGPT can't do for you.
Reverse questions (3 items):
- 3 minimum, 6 maximum. Not one fewer.
- Skip anything answerable from the careers page.
- Favor reveal questions: "What's the team turnover over the last 2 years?", "Why did the previous person in this seat leave?", "How do you handle disagreements between engineering and product?".
On the reference HN thread (356 points), the community insists: reverse questions reveal more about the real culture than 3 visits to the careers page. To go further, read also the 10 most asked interview questions and the STAR method explained.
- ✓Live social reading of the interviewer
- ✓Reasoning out loud, hesitations included
- ✓Quality of your reverse questions
- ✓Agility on an unexpected question
- ✓Visible collaboration mindset in the exchange
- ✗Pick up the panel's non-verbal cues
- ✗Admit a credible, human uncertainty
- ✗Ask a question that reveals genuine research
- ✗Improvise: 'I don't know, but here's how I'd dig'
- ✗Make the panel want to work with you
Post-interview: the 5 items in 48 hours (nobody does)
This is the milestone that differentiates without costing much. Most candidates relax the moment they walk out. That's your opening.
Item 1 — Thank-you email within 24 hours. Personalized with one precise detail from the conversation (a project mentioned, a question the manager asked). No copy-paste. 5-8 lines max.
Item 2 — Written self-debrief. 3 answers where you felt strong, 2 to improve, 1 question you hadn't anticipated. Skip this and you repeat the same misses at your next interview.
Item 3 — LinkedIn. Connection request + 2-line message to the recruiter and the manager, only if the vibe was positive. You're building the network for the next 6-12 months.
Item 4 — Application tracker. Interview date, interviewers, key points, follow-up date set at D+7. Without a tracker, you forget — or you accidentally follow up with the same company 3 times.
Item 5 — Know your rights. The French Code du travail art. L1221-6 requires any question to relate directly to the job (similar protections exist in the US under EEOC rules and in the UK under the Equality Act 2010). The EU AI Act (2024/1689) classifies AI screening systems as "high risk" — you can ask whether an AI filtered you.
- French Code du travail art. L1221-6 — any question must relate directly to the job or to the assessment of skills (similar protections exist under US EEOC rules and the UK Equality Act 2010). You can decline or reframe questions on age, religion, family situation.
- EU AI Act (Regulation 2024/1689), art. 6 + Annex III §4 — recruitment-screening and interview-assessment AI are classified as "high risk". You can ask the recruiter about the nature of the system filtering you.
FAQ
How long does it really take to prepare an interview?
Plan 7 days for a senior or strategic role, 3 days minimum for an operational one. Less than 48 hours and you risk looking improvised on the company — hiring managers detect it within 3 minutes, and HBR 2024 reminds that any approximation read as embellishment is flagged by 63% of recruiters.
What is the ideal length of a STAR answer?
2 minutes max (HBR 2025). Past that, the interviewer drifts. Practice with a timer — it's shorter than you think.
How many questions should I ask at the end?
3 minimum, 6 maximum. Skip anything answerable from the company website. Pick reveal questions: turnover, conflict handling, why the last person in the seat left.
Should I send a thank-you email after?
Yes, within 24 hours, personalized with a precise detail from the conversation. Professionalism signal that can tip the balance between two equivalent candidates.
How do I explain a CV gap or job hopping?
Own the narrative: clear reason (training, personal project, health), lesson learned, pivot to the value you bring now. HBR 2024 warns against over-justifying.
Can I use ChatGPT to prep my answers?
For brainstorming yes, for reciting no. HBR 2025 warns that recruiters detect over-polished answers. Keep your human anecdotes — that's your competitive edge.
What do I do if asked an illegal question (age, kids, religion)?
The French Code du travail art. L1221-6 (and equivalent EU/UK/US rules) require a direct link to the job. Reframe: "If you're asking whether I can work weekends, yes I can." No aggression needed.
How do I know if an AI screened my CV?
The EU AI Act (2024/1689) classifies these systems as "high risk". You can ask the recruiter explicitly — they owe transparency on the system used.
Do I always need to wear a suit?
No. Check LinkedIn and team photos for the actual dress code. One notch above the observed everyday is the safe rule.
What if I blank on a technical question?
Reframe, think out loud, propose a partial path. Recruiters value reasoning over a perfect answer — it's one of the 5 human traits HBR 2025 identifies.
