A complete step-by-step guide covering everything from research to practice — so you walk in confident and walk out with an offer.
Practice with AI Interviewer →Most candidates prepare the wrong things. They memorise generic answers, skim the company website, and call it done. Then they sit in the interview room — or stare at a video call — and discover that being unprepared for follow-up questions is a very different experience from being unprepared for the first one.
This guide covers how to prepare for a job interview properly — not just what to do, but in what order, how deep to go, and what to cut. By the end you'll have a preparation framework you can use for any role, at any company, at any level.
Structured preparation beats cramming every time. Here's how to use the days before your interview effectively.
Go beyond the About page. Find out what problem the company solves, how they make money, who their main competitors are, and what's happened recently — funding rounds, product launches, news coverage, Glassdoor reviews. You're looking to understand the business well enough to have an informed opinion about it.
Read the job description line by line and map each requirement to a specific experience from your CV. Every bullet point is a potential interview question. For each, prepare a concrete example using the STAR method — Situation, Task, Action, Result.
Prepare 4-5 questions to ask at the end of the interview. These signal genuine interest and let you evaluate whether the role is right for you. Also look up your interviewers on LinkedIn — knowing their background helps you connect your experience to what they care about.
This is the step most candidates skip. Reading your notes is not the same as answering questions under pressure. Practise saying your answers aloud — ideally with someone asking you questions, or using an AI mock interview tool. Time yourself. Listen for filler words. Check that your answers feel natural, not rehearsed.
Do a light review of your key examples and the company. Do not try to learn new material. Lay out your outfit the night before, plan to arrive 10-15 minutes early, and bring printed copies of your CV. For video interviews, test your camera and microphone the evening before and find a clean, quiet background.
Effective research is targeted, not exhaustive. These are the four areas that actually come up in interviews.
Understand the business model, the product or service, the main competitors, and any recent news. The goal is to be able to answer "Why do you want to work here?" with genuine specificity — not generic enthusiasm.
Map every requirement in the job description to a specific example from your background. Know what the role is responsible for, who it reports to, and what success looks like in the first 90 days. If the job description doesn't say, prepare to ask.
Look up each interviewer on LinkedIn. Note their background, tenure, and any shared connections or interests. Don't mention that you looked them up, but use what you find to frame your experience in terms they'll care about.
Know the major trends, challenges, and competitive pressures in the sector. This matters most for senior roles and commercial functions, but even junior candidates benefit from being able to discuss the context their future employer operates in.

These are the questions that appear in almost every interview, regardless of role or industry. Prepare for all of them.
This is not an invitation to read your CV. Structure your answer as a 90-second narrative: where you've been, what you've focused on, and why you're here. Move chronologically but only include what's relevant to the role. End by connecting your background to why this specific opportunity interests you.
This question separates candidates who've done their research from those who haven't. Your answer needs to reference something specific about the company — a product decision, a mission statement you genuinely connect with, a recent development. Generic enthusiasm about "the culture" or "the growth opportunity" scores poorly.
Pick a real weakness, not a disguised strength. Interviewers have heard "I work too hard" thousands of times. Describe a genuine development area, briefly explain the impact it's had, and then — crucially — explain what you're actively doing to address it. The self-awareness and growth mindset matter more than the weakness itself.
Use the STAR method. Pick a real example — something that had actual consequences. Show that you understood what went wrong, took responsibility, and changed your behaviour as a result. Candidates who can't name a genuine failure come across as lacking self-awareness.
Answer honestly but tie your ambition to the role. Interviewers want to know you're motivated and that this role is a genuine step toward your goals — not just a stopgap. You don't need a precise five-year plan, but you should be able to articulate the direction you're moving in.
The STAR method is the most effective framework for answering behavioural interview questions — any question that starts with "Tell me about a time when..." or "Give me an example of..."
Set the scene briefly. Give just enough context for the interviewer to understand the stakes — the company, team size, the challenge you were facing. Keep this to 1-2 sentences. Most candidates spend too long here.
Describe your specific responsibility. What were you asked to do, or what did you decide needed to be done? Make your individual ownership clear — interviewers are evaluating you, not your team.
This is the most important part. Walk through exactly what you did, step by step, and why you made those decisions. Use "I" not "we." Be specific — vague actions suggest you either didn't do much or can't remember the details.
Quantify the outcome wherever possible — percentages, time saved, revenue impacted, team size managed. If you don't have numbers, describe the qualitative impact. Always end with what you learned or how it influenced your future approach.
Our AI interviewer asks follow-up questions and tells you exactly what was missing from your answer — structure, specificity, impact, or delivery.

These are the mistakes that cost candidates offers — most are avoidable with proper preparation.
Understanding an answer in your head is very different from being able to deliver it confidently in real-time. Always practise speaking your answers aloud, ideally under mock interview conditions.
Generic answers — "I'm a team player who works hard" — don't win offers. Every answer needs a specific example. If you can't name the situation, the team, the outcome, and the date, the answer isn't ready.
Saying "No, I think you've covered everything" when asked if you have questions signals low interest. Prepare at least 3 thoughtful questions — it's one of the easiest wins in interview preparation.
One evening is not enough time to research a company, prepare and practise 8 STAR examples, and get a good night's sleep. Start at least 3-5 days out.
The job description is a map to what the interview will cover. Every requirement listed is a potential question. Candidates who don't read it carefully often miss obvious preparation opportunities.
Start at least 3-5 days before the interview. Use day one for company research, day two for role research and question preparation, day three for practising answers out loud, and the final day for a full mock interview. Leaving preparation to the night before is the most common mistake candidates make.
Research four things: the company's product, business model, and recent news; the specific role and what success looks like in it; the industry and any major trends; and the people interviewing you via LinkedIn. Most candidates only research the company — researching the role and interviewers sets you apart.
Use the STAR method — Situation, Task, Action, Result — for behavioural questions. For each likely question, prepare a specific example from your work history that demonstrates the skill being tested. Practise saying each answer out loud rather than just writing notes — delivery matters as much as content.
The night before, do a final light review of your key examples and the company, prepare your outfit and documents, plan your route or test your video setup, and go to bed at a reasonable hour. Avoid heavy cramming — if you haven't prepared by the night before, a few extra hours won't save you. Sleep matters more.
Phone interviews require specific preparation. Have your CV and notes in front of you — the interviewer can't see you. Stand up while speaking as it projects more energy. Speak slower than feels natural since there are no visual cues. Have a glass of water nearby. Find a quiet room with good signal and treat it as seriously as a face-to-face interview.
Prepare 3-5 thoughtful questions. The best ones ask about the team culture and how success is measured in the role, what challenges the team is currently facing, and what the interviewer enjoys about working there. Avoid questions about salary, holidays, or anything easily found on the company website.
Preparation is the best cure for nerves — the more you've practised, the less threatening the interview feels. On the day, arrive or log in early, do slow breathing exercises beforehand, and reframe the interview as a two-way conversation rather than an interrogation. Nerves are normal and interviewers expect them.
Speak your answers out loud — not just in your head. Record yourself and watch it back to catch filler words and body language issues. Do a full mock interview with a friend or AI tool so you experience the pressure of answering without knowing what's coming next. Reading notes is not the same as practising.
Reading about interview preparation only gets you so far. The real work is practising under realistic conditions — answering unexpected follow-up questions, managing your time, and getting scored on your actual performance.
