Most interview advice tells you to "be yourself and stay confident." That is not preparation. That is a fortune cookie. Real interview prep is a short list of concrete actions you do in the 7 days before the meeting, and a different short list you do in the 24 hours before. This guide walks you through both, plus the parts most people get wrong: company research, body language, the STAR method, and what to actually do when your hands start shaking in the lobby.

This is the hub article for the full Postulit interview prep cluster. Each section links to a deeper guide if you want to go further.

How to research the company without wasting three hours

The biggest mistake candidates make is reading the entire company website. You do not need to know when the company was founded. You need to know three things: what the company sells, who they sell it to, and what changed in the last six months. That last one is where most candidates lose. A funding round, a new product, a layoff, a new CEO, a strategy pivot. Recruiters mention these things on purpose to see if you noticed.

A tight 30-minute method: 10 minutes on the company's homepage and pricing page, 10 minutes on LinkedIn (the careers page and your interviewer's profile), 10 minutes on Google News filtered to the last 90 days. Stop there. We break this down step by step in our guide on how to research a company before an interview without wasting three hours.

Decoding the job description before you walk in

The job description is the test paper. The questions you will be asked are mostly variations of the bullet points listed under "responsibilities" and "requirements." If the description mentions "experience working cross-functionally with sales and product," you will be asked for a story about that. If it says "comfortable in ambiguous environments," expect a question about a project with no clear brief.

Print the description. Highlight every verb in the responsibilities section. For each verb, write one short story from your past that demonstrates it. That is 70% of your prep right there. Our deeper guide on how to decode a job description before you apply shows the exact annotation method.

Common questions and the STAR method (without sounding like a robot)

There are roughly 12 questions that account for 80% of all interviews. "Tell me about yourself." "Why this company." "Tell me about a time you failed." "Greatest weakness." "Conflict with a coworker." "Most difficult project." You know the list.

The STAR method (Situation, Task, Action, Result) is useful as a skeleton, not a script. Memorising five STAR answers word for word makes you sound stilted and you will freeze the moment a follow-up question goes off-script. Instead, prepare 6 to 8 short stories from your career, each tagged with the qualities they demonstrate (leadership, conflict resolution, technical problem-solving, ownership). When a question comes, pick the closest story and adapt. We cover this in detail in how to prepare for a job interview without memorizing scripts.

The day-before checklist

The 24 hours before an interview are not for cramming new information. They are for reducing friction. You want zero surprises tomorrow morning.

A short version of what to do the night before:

• Reread the job description and your annotated notes one final time.
• Confirm the time, format (in-person, Zoom, Teams), and the interviewer's name.
• Plan your route or test your camera, microphone, and internet.
• Lay out your outfit and put your bag by the door.
• Sleep. Last-minute prep at 1 a.m. costs you more than it gives.

The full version is in the day-before interview checklist: 24 hours to get ready, which goes hour by hour.

What to bring, what to wear

For in-person interviews: 3 printed copies of your CV, a notebook, a pen, ID, and water. Nothing more. For remote interviews: a wired internet connection if possible, headphones with a mic, and a tidy background. The detailed list lives in what to bring to an interview: a no-nonsense checklist for 2026.

On clothing, the rule is one notch above the company's daily dress code. If they wear hoodies, wear a clean shirt and dark trousers. If they wear suits, wear a suit. There is no universal answer; it depends on the industry. Our decision guide for every setting covers tech, finance, healthcare, retail, and creative roles separately.

Body language, voice, and what recruiters actually notice

Most body language advice online is overrated. Power poses in the bathroom do not work. What does work: sitting up straight (which deepens your breathing and steadies your voice), nodding occasionally to show you are following, and pausing for half a second before answering instead of rushing in.

Eye contact is the one signal that almost every interviewer reads, consciously or not. You do not need to stare. Look at the interviewer when they speak, glance away when you are thinking, and return when you answer. The full breakdown of what matters and what does not is in body language in interviews and a more specific piece on eye contact and posture.

Questions to ask back, and handling nerves in the moment

Never leave an interview without asking at least two questions. Not generic ones. Ask about the team's current biggest challenge, how success is measured in the first 90 days, or what the previous person in this role found hardest. These questions show you are evaluating the fit, not begging for it.

For nerves: if your hands shake or your voice trembles, slow down. Take a sip of water. It is normal, and interviewers are far less judgmental about it than you think. The trick is not to eliminate the nerves, but to keep working through them. One slow breath in the elevator, one in the lobby, one before the door opens.

A good interview is a two-way conversation, not a quiz. To get to that conversation, you also need a CV that opens doors and a strong job search method behind it. Our how to find a job pillar covers the broader search process, and how to write a CV covers what gets you into the room in the first place.

Tonight, before tomorrow's interview

Pick one thing. Reread the job description, mark three verbs, and write one short story under each. Twenty minutes. That alone puts you ahead of most candidates. Then put your phone down and sleep. Postulit can help you tailor your CV to the same job description if you want a head start, but tonight, do the prep.
