Preparing for a job interview – a practical guide

What interview preparation means

Preparation is not memorising a perfect performance. It means understanding the role, your relevant experience, questions you may be asked, questions of your own and the practical arrangements.

Thinking through these things makes it easier to talk clearly about your actual background.

Return to the job ad

Read the original job ad again. Identify main responsibilities, required and preferred skills, tools, customer or stakeholder responsibilities, teamwork and independent-work expectations, practical requirements and repeated themes.

An interview often explores the same themes in more depth, but not every line of the ad becomes a question.

Research the employer enough

Use reliable public information such as the employer's own website, descriptions of the role, team, product or service, relevant recent official information and publicly stated work arrangements.

The point is not to memorise corporate marketing. Understand enough to explain why the role interests you, what you understand about the work and what you genuinely want to learn more about.

Choose your strongest examples

Prepare a small set of real examples from work, education, projects, customer work, volunteering, another industry or personal technical projects when relevant.

They can show problem-solving, learning, responsibility, quality, teamwork, customer service, prioritisation, handling pressure, initiative or finishing work. There is no universal number of examples.

Build a clear answer from an example

An optional structure is: situation, task or goal, your own action, then result or learning. This is a clarity tool, not a rigid script or an employer requirement.

Explain your personal contribution clearly, including when the work was shared.

Prepare a short introduction

Questions such as “Tell me about yourself”, “What is your background?” and “Why are you interested in this role?” benefit from a concise professional answer.

Connect your current situation or background, relevant skills or experience and why this role. Avoid a full life story.

Why this role

Real motivation can relate to responsibilities, the field, product or service, customers, technologies, learning direction, type of work or your relevant strengths.

Generic praise for the employer is not a substitute for a true reason.

Show strengths with evidence

Rather than only saying “I am careful”, explain where carefulness showed and what you did.

Development areas and weaknesses

Choose a genuine, manageable development area rather than a fake weakness or dramatic self-criticism. Explain what you noticed, what you are doing about it and what has already improved.

You do not need to disclose irrelevant sensitive personal information.

Missing experience or skills

If you lack something in the ad, do not invent it or pretend the gap is absent. Identify adjacent experience, transferable skills, education, projects or how you would learn the missing area.

Clearly distinguish professional use from study or project practice.

Interviewing as a career changer

Use a clear line: previous career → transferable skill → relevance to the new role → concrete evidence in the new field. Your previous career is not wasted.

Precision, responsibility, quality control, customer service, teamwork, independent work, problem-solving and planning can matter, but they are not direct professional experience in the new field.

Behavioural and situational questions

Common themes may include solving a difficult problem, disagreement, a mistake and what you learned, competing priorities, learning something new, a customer issue, pressure or receiving feedback.

Use real examples you can explain rather than canned “perfect” answers.

Technical or practical interviews

Some roles may include technical questions, work samples, coding tasks, case tasks, portfolio discussion or practical demonstrations. Not every role does.

Review your own work, know what you personally implemented and explain decisions. Say when you do not know, think aloud when appropriate and clarify task assumptions.

Using AI to prepare for an interview

AI can generate practice questions from a job ad, run a mock interview, critique clarity, shorten answers and identify unsupported claims.

It must not invent experience, fabricate technical knowledge or achievements, or tell you to claim something you cannot explain. Verify everything yourself.

Remote interviews

Check your connection, meeting link, camera and microphone if required, charger or power, a reasonably quiet environment, display name, and that documents and notes are available. Join with enough time to resolve technical issues.

Expensive equipment or a perfect background are not required; a professional conversation matters more than cosmetic perfection.

In-person interview practicalities

Verify the address, route and travel time, contact person, arrival instructions and requested documents or items. Charge your phone and allow a reasonable buffer.

Follow the employer's instructions rather than treating any arbitrary arrival time as universal.

Salary and salary expectations

Salary practices vary by employer, role, market, applicable collective agreement or compensation structure and experience. Check any range in the job ad and credible role-relevant salary information.

Know an expectation you can explain based on the responsibilities and your experience. If asked, answer truthfully; no negotiation tactic works in every situation.

Prepare your own questions

Useful areas include day-to-day work, the team, first-month priorities, tools and processes, onboarding, expectations, how success is assessed, development opportunities and next recruitment steps.

The interview is also your opportunity to assess whether the job fits you. Avoid questions whose answers are already obvious unless clarification is genuinely needed.

Nerves do not prevent a good interview

It is normal for an interview to feel important. Pause before answering if useful, ask for a question to be repeated or clarified, and use short notes where appropriate.

You do not have to answer instantly. Preparation can reduce cognitive load.

If you do not know the answer

A truthful response is better than invention, especially in technical interviews. Say what you know, state what you do not know and explain how you would find out or approach the problem.

This shows your thinking without bluffing.

After the interview

Make brief notes while the conversation is fresh, record promised follow-ups, send requested materials and follow the employer's stated timeline.

A concise thank-you or follow-up can sometimes be appropriate, but it is not universally required or a guarantee of an outcome.

Common mistakes

Avoid not rereading the job ad, using only abstract adjectives, memorising robotic scripts, exaggerating experience, not knowing your own CV or application and preparing no questions.

• do not give answers unrelated to the role
• do not pretend to know something you do not
• do not forget practical arrangements
• speak professionally about previous employers: focus on facts and what you seek next rather than venting

Final checklist

Keep final notes concise.

• prepared real examples and role motivation
• can explain CV and application claims
• identified meaningful gaps honestly
• prepared my own questions
• checked logistics, documents and links
• considered salary expectations if relevant
• checked remote technology if relevant
• no invented claims
