Interview preparation

How to prepare for an interview, in the order you will actually do it

Interview preparation is four jobs: know the company, know the job description, match your resume to it, and rehearse the questions everyone gets. This plan puts those jobs on a timeline, from one week before to the follow-up email, with a free tool for each step.

Every tool linked here is free and runs in your browser. Nothing is uploaded.
The short answer

How to prepare for an interview

Read the job description twice and underline every skill it names. Read your resume and find where each of those skills shows up. Prepare eight standard answers and three short stories that prove your points. Prepare three questions to ask them. Test your camera and microphone the night before. That is the whole method. The rest of this page puts it on a calendar.

One week before

Research the company, read the job description, map your resume

Research the company, one hour, not one day

You need four facts: what the company sells, who buys it, what changed for them this year, and what the team you are joining does inside that. Get them from the company website, its careers page, and one recent news item. Write them in five lines. Any more and you will not remember it in the room.

Read the job description like a test paper

Every line in a job description is a question they are going to ask, in some form. "Experience with cloud deployments" becomes "tell me about a deployment you ran". Paste the posting into the job description to questions tool and it lists the questions that role tends to get. It matches in your browser and uploads nothing.

Map your resume to the posting

Put the job description and your resume side by side. For each skill in the posting, find the line in your resume that proves it. Where nothing matches, decide now: is there a story you forgot to write down, or is it a real gap you should admit honestly? The resume vs job description match tool shows the keywords the posting uses that your resume does not.

Freshers, the same steps apply, but the resume is projects, coursework and internships. The fresher preparation guide walks through that version.

Answers

Prepare the eight questions everyone gets

You can predict most of a first-round interview. Write one short answer for each of these and say each one out loud until it sounds like talking, not reading.

  1. Tell me about yourself. Build it with the tell-me-about-yourself builder.
  2. Why do you want this job?
  3. Why should we hire you?
  4. What is your greatest weakness?
  5. Tell me about a time you failed.
  6. Tell me about a conflict with a colleague and how you handled it.
  7. Where do you see yourself in five years?
  8. Do you have any questions for us?

The common interview questions page gives an answer frame for each of these and seventeen more. Tricky HR versions, like salary and gaps in your resume, are in the HR questions vault.

Say: "I am a [role] with [number] years in [area], and the thing I keep choosing to do is [the part of the job that matches this posting]."

Then: one project that proves it, the result it had, and why this role is the next step.

Stories

Three STAR stories cover most behavioral questions

Behavioral questions start with "tell me about a time". The answer is a short story with four parts: the Situation, your Task, the Action you took, and the Result. Most people need only three stories, chosen so that together they show a win, a failure you learned from, and a time you worked with a difficult person.

Write each story in six sentences. The STAR answer builder makes you fill each part and tells you when the Action is too vague or the Result is missing. Then practise saying each story in under two minutes. A story that runs long loses the interviewer before the result.

Say: "The clearest example is [project], where [one-line situation]."

Then: what you were responsible for, the two things you actually did, and the result in one measurable sentence.

Two days before

Run a mock, then prepare your own questions

Do one mock interview out loud

Reading answers in your head is not practice. Ask a friend to read the eight questions to you over a video call, or use the 60-second mock interview if nobody is free. Record yourself once. You will hear filler words and one answer that is twice as long as it should be. Fix those two things and stop. Do not rewrite everything.

Prepare three questions to ask them

"Do you have any questions?" is not a courtesy. It is the last scored answer. Prepare three that show you listened and want the job:

  • "What would a strong first ninety days look like in this role?"
  • "What is the hardest part of this job that the posting does not mention?"
  • "How does the team decide what to work on next?"

Never ask about salary or holidays in a first round unless they raise it. The HR interview questions guide covers what to say when they do.

Check where you stand

The interview readiness quiz takes under a minute and tells you which of these steps you have actually done, not just read about.

The night before

Tech check for a video interview

Most video interview disasters are avoidable the night before. Go through this list once:

  • Open the exact meeting link they sent. If it needs an app or an account, install it now, not five minutes before.
  • Test camera and microphone in that app. Check that the camera is at eye level and your face is lit from the front, not from a window behind you.
  • Use headphones. They stop echo and they stop the interviewer hearing themselves.
  • Charge the laptop and keep the charger plugged in during the call.
  • Close every app that can pop a notification. Put your phone face down and on silent.
  • Print or open your resume, the job description and your five research lines, so you can glance without searching.
  • Decide what you will wear and put it out. Then sleep. A tired mind cannot find the first sentence.

The checklists and templates page has this list as a printable one-page checklist.

One hour before

Warm up, then stop preparing

  • Read your eight answers once, out loud. Do not edit them.
  • Read your five company lines once.
  • Drink water. Eat something small. An empty stomach makes a shaky voice.
  • Ten minutes before, join the call and sit in the waiting room. Being early is a free point.
  • Then close everything except the call, your notes, and whatever tool you use during the call. Nothing else.
During

In the interview, and what to do when you get stuck

Listen to the whole question before you start. Answer the question they asked, not the one you prepared, and keep each answer under two minutes. Look at the camera when you speak, not at your own picture. It is fine to pause for three seconds to think. It reads as calm, not as slow.

When you do not know the answer

Do not bluff and do not go silent. Say what you do know, say how you would find the rest, and ask a question back if you need more detail. There is a whole guide on what to say when you do not know the answer, with sentences you can use as they are.

Say: "I have not worked with [thing] directly, but I have done [nearest thing], and here is how I would approach it."

Then: the first two steps you would take, and the question you would ask to check you are on the right track.

The most common mistakes in the room are small and fixable. The interview mistakes guide lists them in order.

After

The follow-up most people skip

Within the hour, write down every question they asked and how you answered. That list is your preparation for the next round, and for the next company. The same day, send a short thank-you email: two lines, one thing you learned in the conversation, and that you are still interested. No essay.

If they gave a date for a reply and it passes, wait two working days and send one polite line asking about the timeline. Then move on to the next interview. Preparation is a habit, not a one-time event.

Two halves

Where ClapAssist fits

Everything above is the preparation. It has to be yours, and nothing on this site changes that. What ClapAssist adds is the live half: during the video call it listens on your own computer and shows the shape of the answer from the resume and job description you prepared, one sentence to say first, then the points. It is there for the moment you prepared for a question and still cannot find the first line. The AI interview assistant page explains how it works and what it does not do.

Questions

Questions people ask

How many days do you need to prepare for an interview?

One week is comfortable if you follow a plan: research and resume mapping early, answers and STAR stories mid-week, a mock two days before, a tech check the night before. With one day, do the job description mapping and the eight standard answers, and skip the rest.

What should I prepare first for an interview?

The job description. Every line in it is a question in disguise. Read it twice, underline the skills, and find the line in your resume that proves each one. The answers and stories follow from that mapping.

What are the most common interview questions to prepare?

Tell me about yourself, why this job, why should we hire you, your weakness, a failure, a conflict, where you see yourself in five years, and do you have questions for us. The common interview questions page gives a frame for each.

How do I prepare for a video interview?

Open the exact meeting link the night before, test camera and microphone in that app, use headphones, put the camera at eye level with light on your face, close notifications, and join ten minutes early.

What questions should I ask at the end of an interview?

Ask three: what a strong first ninety days looks like, the hardest part of the job the posting does not mention, and how the team decides what to work on. Leave salary and holidays for later rounds unless they raise it.

What do I do if I do not know the answer in an interview?

Say what you do know, explain how you would find the rest, and ask a clarifying question. Never bluff and never go silent. The guide on what to say when you do not know the answer gives exact sentences.

Should I send a thank-you email after an interview?

Yes, the same day. Two lines: one thing you learned in the conversation and that you are still interested. Keep it short.
