The preparation plan
Seven steps, from the invitation to the day itself
Start as soon as the invitation arrives. Steps three and four take the most time, and they are the ones that decide how the interview goes.
Only have 24 hours?
Do steps 2, 3 and 6 fully, prepare three STAR stories instead of six (a success, a failure and a conflict), practise "Tell me about yourself" out loud twice, and check the route or link tonight. That takes about two hours and covers most of what you will be asked. Skip deep research: one recent fact about the company is enough.
1Research the company, not just its homepage
45 minutes
Find out what they sell, who buys it, how they make money, and what has changed in the last six months: a new product, a funding round, a new CEO, layoffs, an expansion. Look up the people who will interview you on LinkedIn.
The "About us" page tells you what they want you to think. Recent news, their job listings, customer reviews and the LinkedIn profiles of people in the team tell you what is really going on. One specific, recent fact mentioned in the interview does more than ten compliments about their "mission".
2Turn the job posting into a checklist
20 minutes
Print the posting or copy it into a document. Mark every requirement and every responsibility. These are the topics your questions will come from, usually in the same order of importance.
Next to each requirement, write one thing you have done that proves it. Where you have nothing, decide now what you will say honestly: a related experience, or how you would learn it fast. A gap you have thought about sounds calm. A gap you discover in the room sounds like panic.
3Re-read your CV as if you were the interviewer
20 minutes
Every line on your CV is a possible question. Read the version you actually sent, not the one you have now, and prepare to talk for a minute about every bullet, every number and every gap between jobs.
Interviewers usually have your CV in front of them and go down it from the top. If a number is on the page, expect "How did you get to that?" If you sent different versions to different companies, check which one this company has. A CV tailored to the posting also makes the interview easier, because it already points to your best examples.
4Build a bank of five or six STAR stories
60 minutes, the step that matters most
Pick five or six real situations from your work: a success, a failure, a conflict, a time you led something, a time you had to learn fast, and a time you went beyond your role. Write each one in the STAR format: situation, task, action, result.
Six good stories answer about thirty different questions, because one story about fixing a late project works for "a challenge", "working under pressure", "a time you showed initiative" and "a mistake you learned from". Keep each story under two minutes. Spend most of that time on the action, and end with a number or a clear result.

5Practise out loud, not in your head
45 minutes
Say your answers out loud, ideally to another person or into your phone camera. Answers that seem fine in your head are usually twice as long and half as clear when spoken.
Record yourself answering "Tell me about yourself" and two STAR stories. Watch it once. Most people find they start too slowly, say "basically" a lot, and forget to say the result. Fix those three things and you are ahead of most candidates. Do not learn answers word for word: know the points, and let the sentences be different each time.
6Prepare three questions to ask them
15 minutes
At the end you will be asked "Do you have any questions for us?" Have three ready, about the work itself, the team, and how success is measured. Never say "No, I think you covered everything."
Good questions show you are already imagining yourself in the job. Leave salary, holidays and remote work for later rounds or for HR, unless they bring them up first. Write your questions down and bring them. Looking at your notes here is completely normal.
7Sort out the logistics the day before
15 minutes
For an in-person interview: the exact address, the route, how long it takes, and who to ask for at reception. For a video interview: the link, the app, your camera, microphone, light and background. Test all of it the day before, not five minutes before.
Plan to arrive ten minutes early, not thirty. Waiting in reception for half an hour makes you more nervous and makes the host feel rushed. Prepare what you will wear, charge your phone, and keep a printed or digital copy of your CV nearby so you can see exactly what they see.
