# How to Prepare for an Interview: A Day-by-Day Plan

> Start about a week out. Research the company and the people you'll meet, match your experience to what the role needs, practice your answers out loud and write your questions. Keep the day before for logistics and rest, not cramming.

## Key takeaways

- Preparing for a job interview takes about a week of short sessions: research first, then stories, then practice out loud.
- The most useful interview prep is matching each requirement in the job description to a real example from your work.
- Practicing answers out loud, not just reading them, is what makes them sound natural in the interview.
- The day before an interview is for logistics and rest; new research the night before rarely helps.
- Recruiter screens, video calls, internal interviews and internship interviews each need small changes to the same core prep.

## How long should you spend preparing for an interview?

For a first-round interview, three to five hours spread over a few days is enough. For a final round with a presentation, plan on a week of evenings.

Spreading it out matters more than the total. Your answers get better when you've had time to forget them and remember them again, and a few short sessions are easier to fit around a job than one long one.

## A week before: research and match

Most of your preparation happens here. The aim is to understand what the company needs and line up proof that you've done it.

**Research the company.** Read their site, their last few months of news and, if they're public, their latest earnings release. For marketing roles, look at what the brand actually does: its last month of posts on its main social account, the ads it's running (the Meta Ad Library and Google's Ads Transparency Center are public), what people say in the comments, and how it compares with its main rival. Our guide to [researching a company before an interview](/guides/how-to-research-a-company-before-an-interview/) walks through where to look.

**Research the people.** Look up each interviewer on LinkedIn. Note what they've worked on and how long they've been there. It tells you what each of them is likely to care about.

**Match your experience to the posting.** Go through the job description line by line. For each requirement, write down one example from your career that proves it, with a number if you have one. Where you don't have a match, plan an honest bridge: a related thing you've done and how you'd close the gap. Nobody matches every line, and interviewers don't expect it.

## Four or five days before: build your stories

Interviewers remember stories, not lists of skills. Pick six to eight examples that together cover what the role needs.

For each one, note the situation, what you did, and the result. Keep each to about two minutes when spoken. The same story can often answer several questions, so you don't need one for every possible question. Note them as bullets, not scripts, so you tell them in your own words each time; your personality is part of what they're hiring, and it shows most when you're talking, not reciting.

Have these ready in particular:

- A 60-second career summary for [tell me about yourself](/guides/tell-me-about-yourself/)
- Why this company and this role ([how to answer that](/guides/why-do-you-want-to-work-here/))
- A campaign or program you're proud of, with results
- Something that didn't work and what you learned
- A time you disagreed with someone senior
- A real weakness and what you do about it ([how to answer](/guides/what-are-your-weaknesses/))

## Three days before: practice out loud

Reading your notes isn't practice. Say your answers out loud, ideally to another person, or record yourself on your phone and listen back.

You'll hear where you ramble, where you skip the result, and where you use jargon the interviewer won't share. First attempts almost always run long, and that's normal; cut until each answer makes its point in under two minutes.

Practice the questions for your level and discipline too. Our [marketing interview questions](/interview-questions/) cover common ones by role.

## Two days before: write your questions

Prepare six to eight questions, knowing you'll ask three or four. At least one should come from your research, not from a list. See [questions to ask the hiring manager](/guides/questions-to-ask-the-hiring-manager/).

## The day before: logistics, not cramming

Check the time, the address or video link, and who you're meeting. Plan what you'll wear (see [what to wear to an interview](/guides/what-to-wear-to-an-interview/)). For a video call, test your camera, microphone and lighting in the room you'll use.

Read through your stories once, then stop. A tired candidate does worse than an under-rehearsed one.

## The hour before

Arrive ten minutes early, or be at your desk with the call open five minutes before. Have water, your notes and the job posting in reach.

Look over three things: the company's most recent news, the one or two points you most want to get across, and your first question. Then put the notes away.

## What to bring

For an in-person interview:

- A few printed copies of your resume
- A notebook and pen
- Your list of questions
- For a final round, a printed one-page plan or the slides you're presenting

## How do you prepare for different kinds of interviews?

The core prep stays the same for every interview: research, stories, practice and questions. What changes is the emphasis.

| Interview | What to add to your prep |
|---|---|
| Recruiter or phone screen | A tight 60-second pitch, your salary range and your timeline. See [phone screen interview questions](/guides/phone-screen-interview-questions/). |
| Video interview | Test your camera, light and sound in the room you'll use, and keep notes off screen. See [video interview tips](/guides/video-interview-tips/). |
| In-person interview | Plan the route, arrive 10 minutes early and bring printed copies of your resume. |
| Internal interview | Prepare as seriously as for an outside role: show results the panel may not know about and say what you'd do differently in the new job. |
| Internship interview | Lean on coursework, projects and part-time jobs, and show what you've done on your own to learn marketing. |
| Panel or final round | Map each interviewer to what they'll care about. See [panel interview tips](/guides/panel-interview-tips/). |

## Can you use ChatGPT or AI to prepare for an interview?

Yes, as a practice partner rather than a script writer. AI tools are useful for generating likely questions from the job description, asking you follow-ups and pointing out where an answer runs long.

Keep the stories and the numbers yours. Interviewers ask follow-ups, and an answer you didn't build from your own experience is hard to defend. A good routine is to answer out loud, paste in what you said, and ask for one thing to tighten. Our [mock interview questions](/guides/mock-interview-questions/) give you a question set to start with.

## A one-page prep sheet

Fill this in for each interview. It's the one thing to glance at before you walk in.

```text
ROLE: [title] at [company] · Meeting: [names and titles] · [date, time, link or address]

WHAT THEY NEED (top 3 from the posting)
1. [need] → my proof: [example + number]
2. [need] → my proof: [example + number]
3. [need] → my proof: [example + number]

WHAT I KNOW ABOUT THEM
- [one fact about the brand or business]
- [one recent change or piece of news]

MY GAP AND MY BRIDGE
- Gap: [what I haven't done] → Bridge: [closest thing I have done, and how I'd close it]

MY QUESTIONS
1. [from research]
2. [about success in the role]
3. [about next steps]
```

## FAQ

### What is the most important thing to do before an interview?

Match your experience to the job description. Knowing which of your examples proves each requirement makes every answer sharper, whatever the question.

### How do I prepare for an interview the night before?

Check logistics, plan your outfit, read through your key stories once and get some sleep. The night before is too late for new research.

### How do I prepare for a video interview?

Prepare the content the same way, then test your setup in the room you'll use: camera at eye level, light in front of you, a quiet space and a backup plan if the connection drops. Our [video interview tips](/guides/video-interview-tips/) cover the rest.

### What are the most common interview questions?

"Tell me about yourself", "Why do you want to work here?", "Why should we hire you?", "What are your weaknesses?" and behavioral questions that start "Tell me about a time…". Prepare those first; our guides to [tell me about yourself](/guides/tell-me-about-yourself/) and [behavioral interview questions](/guides/behavioral-interview-questions/) are good places to begin.

### Should I memorize my answers?

No. Memorize the stories and the numbers, not the words. Memorized answers sound recited and fall apart when the question is phrased differently, while a story you know well comes out naturally in your own voice.
