How long should I prepare for a job interview?

Plan for at least several hours spread over a few days: one session for researching the job and company, one for preparing stories, and two or three for practising answers aloud. More senior or technical roles need more time.

What is the best way to practise for an interview?

Answer realistic questions out loud and get feedback. A friend, a mentor or an AI mock interview can ask follow-up questions, which is the part books and question lists cannot give you.

Should I memorise my answers?

No. Memorised answers sound stiff and fall apart when the question is phrased differently. Memorise your key stories and facts, and speak naturally around them.

Job interview preparation: a step-by-step guide

Good job interview preparation is mostly about practice, not luck. Candidates who know their field still lose offers because they never rehearsed saying their answers aloud. This guide walks through what to do in the week before an interview, in the order that works best.

1. Understand the job before anything else

Read the job advertisement slowly and underline every skill, tool and responsibility it names. These are the things the interviewer will test. Most questions you are asked will map back to a line in that advertisement.

Then compare the list with your own resume. Where you have clear experience, note a project or result to talk about. Where you have a gap, decide in advance how you will answer honestly: what you have done that is close, and how quickly you can learn the rest.

2. Research the company and the people

Spend thirty minutes on the company website, recent news and, if possible, the interviewers' professional profiles. You want to be able to say in one or two sentences what the company does, who its customers are and why the role matters to it.

What does the company sell or provide, and to whom?
What did it announce or launch recently?
What would success in this role look like in the first six months?
Which two or three questions will you ask the interviewer at the end?

3. Prepare six stories, not sixty answers

Interviewers rarely want memorised scripts. Instead, prepare six real stories from your experience: a time you solved a hard problem, worked in a team, handled a mistake, led or influenced someone, learned something quickly, and dealt with pressure or a tight deadline. Each story can be reshaped to answer many different questions.

Write each story using the STAR method (Situation, Task, Action, Result) so it has a clear beginning, middle and measurable end.

4. Practise out loud, not in your head

Silent preparation feels productive but hides the real problems: rambling, filler words such as "um" and "like", speaking too fast, and losing your thread halfway through an answer. Answering questions aloud, ideally with someone or something that asks follow-up questions, exposes those habits while there is still time to fix them.

An AI mock interview tool can play the interviewer when no friend is available: it asks questions based on your resume and the job advertisement, follows up on what you actually say, and gives feedback afterwards.

5. Prepare the practical details

For an in-person interview, plan your route and arrive early. For an online interview, test your camera, microphone and internet connection the day before, choose a quiet room with light facing you, and keep a glass of water nearby. Have a copy of your resume, a notebook and your prepared questions ready.

6. On the day: manage nerves and answer well

Nerves are normal and even useful. Slow your breathing before you start, pause for a second before answering, and speak a little slower than feels natural. If you do not understand a question, ask for it to be repeated. If you do not know something, say so honestly and explain how you would find out.
