How to Prepare for a Job Interview

Know what to expect

Read the invitation carefully. Note the date, time and time zone, the format (in person, phone or video), who will interview you and how long it is expected to last. Some organizations use several rounds: a short screening call, a structured interview with a panel, and sometimes a practical task or presentation. If anything is unclear, it is fine to ask the recruiter politely, for example who you will be meeting and whether you should prepare anything.

Research the organization and the role

Read the job description again and underline the main responsibilities and requirements. Then learn about the organization: what it does, who it serves, its recent projects or publications and, for international organizations, the countries and sectors it works in. Use the organization's own website and reports. You are not trying to memorize facts, but to be able to explain, in your own words, why this organization and this role interest you.

Prepare a short answer to "Why do you want this job?" that connects your experience and interests to specific parts of the role. Generic answers are easy to spot.

Prepare examples, not speeches

Most interviews include questions about past experience, such as "Tell me about a time you worked in a team" or "Describe a challenge you solved". A useful way to organize your answer is to explain the situation, your task, what you did, and the result. Choose four to six real examples from work, studies, volunteering or projects that show skills the job needs, such as communication, problem solving, reliability, leadership or technical ability. Practice telling each in about two minutes, with concrete details and an honest outcome, including what you learned.

Do not invent or exaggerate. Interviewers often ask follow-up questions, and a real example holds up under them.

Common questions to practice

• "Tell me about yourself." Give a short summary of your background, what you do well and why you are applying. About one to two minutes is enough.
• "Why do you want to work here?" and "Why this role?"
• "What are your strengths?" Choose real strengths that fit the job and back each with a short example.
• "What is a weakness you are working on?" Name a genuine one and explain what you are doing about it.
• "Tell me about a time you made a mistake or faced a difficulty."
• "Where do you see yourself in a few years?" Show interest in developing, without promising more than you can.
• Questions about practical matters, such as availability, notice period, working hours, work permits or expected salary. Think about your honest answers in advance.

Technical and practical parts

Many jobs include a task, a case question or a technical discussion. Review the skills and tools named in the job description, and refresh the basics you have not used recently. If you are asked something you do not know, say so calmly and explain how you would find the answer. Thinking aloud shows how you approach problems, which is often what the interviewer wants to see.

Video and phone interviews

• Test your camera, microphone, internet connection and the meeting software a day before, and join a few minutes early.
• Choose a quiet place with a plain background and good light on your face, and silence notifications.
• Look at the camera when you speak, and keep a copy of your CV and a few notes in view. Do not read answers word for word.
• Keep a phone number or email of the recruiter, in case the connection fails.
• With time differences, double-check the interview time in your own time zone.

Prepare your own questions

At the end, you will usually be asked whether you have questions. Prepare two or three that show real interest, for example about what a successful first six months looks like, how the team works together, how performance is reviewed, or what the next steps in the process are. Avoid asking about holidays or pay in a first conversation unless the interviewer raises them.

On the day and afterwards

• Arrive or log in early, dress in a way that suits the organization, and bring copies of your CV and any documents requested.
• Listen to the whole question before answering. It is fine to pause for a moment to think.
• Be polite to everyone you meet, and be honest about what you know and do not know.
• Within a day, send a short thank-you message to the recruiter, mentioning something specific you discussed and confirming your interest.
• If you do not hear back by the date you were given, a polite follow-up is appropriate.
