How to Prepare for a Job Interview

Interview prep is the rare task where 80% of the value comes from the first 90 minutes of work. Diminishing returns hit fast. The candidates who walk in calm and clear are not the ones who studied for a week; they are the ones who covered four specific bases. Here is how to prepare for a job interview properly, whether you have two days or two weeks.

The four bases of any interview prep

1. Know the company at a paragraph level

What they do, who their customers are, recent product or business news, what stage they are in (early growth, scale-up, mature). Read their last six months of blog posts, scan their LinkedIn for recent hires, look at their news mentions, look at one Glassdoor or Blind page for the company culture rumour-check.

You do not need to be an expert. You need to be able to answer "so why are you interested in us?" with one sentence that proves you read more than the careers page.

2. Know the role at a sentence level

Read the job description twice. List the three to five concrete things this person will do. Then prepare one specific story from your career for each one. The interview almost always asks "tell me about a time you..." — and the prepared candidate has the right story queued up while everyone else is improvising.

3. Rehearse the standard questions

Eight questions cover 80% of all interviews. Have a version of an answer for each, ideally rehearsed out loud — not silently in your head:

• Walk me through your background / tell me about yourself.
• Why this role, why this company, why now?
• Tell me about a project you're proud of.
• Tell me about a time something went wrong / how you handled conflict.
• What's a weakness you're working on?
• Why are you leaving your current role?
• Where do you see yourself in 3–5 years?
• Do you have any questions for us?

4. Have three smart questions ready

The end-of-interview "any questions?" is judged. Generic ones ("what's the culture like?") signal lack of preparation. Specific ones signal seriousness:

• "What does success in this role look like at the 6-month mark?"
• "What's the biggest challenge the team is facing right now?"
• "How has the role evolved since the last person was in it?"

The "tell me about yourself" answer

The most common opener and the most commonly botched. The right structure is 90 seconds, three beats:

• Where you are now (current role and what you focus on).
• How you got there (one or two career arcs that shaped you).
• Why this role connects to what's next.

Avoid: chronological CV from age 17, hobbies and pets, a list of skills. The interviewer has your CV. They want a narrative, not a recitation.

The STAR method (use it, don't worship it)

For "tell me about a time you..." questions, the STAR structure (Situation, Task, Action, Result) keeps stories concise. Two important refinements most candidates miss:

• Spend 60% of the time on Action. The story is about you, not the situation. Most candidates over-set the scene.
• End with a quantified Result if at all possible. "Reduced error rate by 30%" beats "the team felt better about it."

Cap each story at 2 minutes. Long answers are remembered as rambling.

The week-of preparation

• Reread the job description.
• Look up the interviewers on LinkedIn — names, role context, any shared connections.
• Choose your outfit and lay it out.
• Plan logistics — route, parking, video setup. Test the camera and audio if remote.
• Practice the "tell me about yourself" out loud once.

The day-of routine

• Eat properly. Low blood sugar will sabotage anything.
• Arrive 10 minutes early; do not enter 30 minutes early — that puts the interviewer under awkward pressure.
• Bring a printed copy of your CV, even if it is a video call. The discipline keeps you organised.
• Five minutes of deep breathing or a short walk before the interview drops the cortisol meaningfully.

What to skip

• Memorising every potential question and rehearsing word-for-word answers. You sound robotic. Outline points, not scripts.
• Lying or exaggerating your CV. Interviewers in 2026 reference-check more than ever, and AI tooling makes verifying claims easier than ever.
• "Power posing" in the bathroom. The science behind it has not held up. Your normal calm posture is fine.
• Asking about salary in the first round. Save for screening or offer stage. Bringing it up too early signals priorities backward.

The follow-up that quietly matters

A short thank-you email within 24 hours, mentioning one specific thing from the conversation. Three lines, not a wall of text. About a third of candidates skip this; doing it positions you well in the close decision.

Bottom line

Preparing for a job interview in 2026 is not a marathon. Ninety minutes of structured prep, plus a 30-minute day-of routine, beats a week of scattered studying. Know the company, know the role, rehearse eight standard questions, prepare three sharp questions of your own. Walk in calm, sit up straight, listen carefully, give specific stories with specific results. The candidates who do this consistently get most of the offers — not because they are smarter, but because they came ready while half the room came hopeful.
