What to Expect: Interview Types & Formats

Understanding what type of interview you are walking into shapes everything from your tech setup to how you present yourself. The format influences the evaluation focus, preparation priorities, and even how much of your body language is visible to the panel.

Common Interview Formats

In-Person Interviews

• Traditional interview format conducted at the employer’s office.
• Usually lasts around 40 minutes.
• Evaluates handshake, posture, body language, and workplace interaction.
• Strongly focuses on cultural fit and interpersonal chemistry.

Phone Interviews

• Commonly used for initial screening rounds.
• Focuses on voice clarity, tone, and communication skills.
• Tests your ability to explain ideas clearly without visual interaction.
• Emphasises concise and structured responses.Read More

Video Interviews

• Widely used, with 86% of organisations adopting virtual interview technology.
• Combines elements of both phone and in-person interviews.
• Assesses communication, energy, camera presence, and technical readiness.
• Requires comfort with digital platforms and virtual interaction.

Assessment Centre Interviews

• Includes group discussions, presentations, case studies, or problem-solving tasks.
• Evaluates teamwork, leadership, collaboration, and critical thinking.
• Tests how you perform under observation and in team settings.
• Commonly used for graduate programs and managerial roles.

How Preparation Differs by Format

Preparation is not one-size-fits-all. For video interviews, test your internet speed, frame your camera at eye level, check your lighting, and have a backup device charged and ready. Log in 30 minutes early to troubleshoot any link issues. For phone interviews, find a quiet space, keep your CV and notes in front of you (they cannot see you reading), and speak slightly slower than usual to compensate for audio-only communication.

Body language matters enormously, but visibility varies. Nonverbal communication accounts for 55% of interview success, encompassing everything from posture to facial expressions. In video calls, only your upper body is visible, so hand gestures within frame and eye contact with the camera (not the screen) become critical. In phone interviews, body language still matters; standing or sitting upright genuinely changes your vocal energy and confidence, even if no one can see you.

For assessment centres, observe group dynamics. Panels watch how you listen, build on others’ ideas, and handle disagreement. Prepare by practising collaborative problem-solving scenarios and being mindful of speaking time; dominating the conversation is as damaging as staying silent.

Analyse the Job Description and Your CV

The interview is not a blank-slate conversation. It is a continuation of the story you started with your application. Your CV got you in the door; now you need to bring those bullet points to life with evidence, context, and personality. That starts with mapping what the employer needs to what you have already proven you can deliver.

Extract Top Competencies from the Job Description

Read the job description at least twice, the first time for overall understanding, the second time with a highlighter. Identify five to seven core competencies, the non-negotiables the role demands. These will be a mix of hard skills (e.g., proficiency in Python, experience with budget management) and soft skills (e.g., stakeholder communication, adaptability). Pay attention to language that repeats across sections, as it signals priority.

Do not stop at stated requirements. Look for implied expectations. A role emphasising “fast-paced environment” suggests they value quick decision-making and stress tolerance. “Cross-functional collaboration” hints that they will ask about teamwork and conflict resolution. These clues tell you which stories to prepare. Alarmingly, 47% of candidates fail interviews due to insufficient knowledge of the company, a statistic that underscores how often applicants skip this foundational step.

Map Your CV Evidence to Each Requirement

Create a simple two-column table. In the left column, list each key competency from the job description. In the right column, write the specific CV bullet point or experience that proves you have it, then add a one-sentence story angle you can expand on during the interview.

For example, 

If the role requires “project management experience” 

Your matching evidence might be: “Led a cross-departmental initiative to streamline vendor onboarding, reducing processing time by 30%. Story angle: navigating resistance from the finance team and winning buy-in.”

This exercise ensures consistency between your written application and your spoken answers. Interviewers cross-check your CV against what you say; contradictions or vague responses to your own listed achievements raise red flags.

Polish Your LinkedIn Profile

Interviewers will look you up. Almost 97% of HR and staffing professionals use LinkedIn in their recruiting efforts, and candidates with comprehensive profiles have a 71% higher chance of getting a job interview. Before your interview, refresh your profile to ensure it reflects the same language, skills, and achievements you emphasise in your application.

Update your headline if needed, add recent projects, and ensure your summary aligns with the narrative you will present in person. Consistency across platforms signals professionalism and attention to detail.

Research the Company, Role & Interviewers

Walking into an interview without understanding the company is like showing up to a dinner party and asking the host what they do for a living. It signals disinterest, and hiring managers notice. Thorough research is not optional; it is the baseline expectation. 70% of hiring managers say being unprepared is a common mistake candidates make during interviews.

Five Essential Research Sources

Effective company research helps you give more personalised and confident interview answers.

1. Company Website
   Read the About page, mission statement, product details, and recent press releases to understand the company’s goals, values, and priorities.
2. Social Media Platforms
   Explore LinkedIn, Twitter, and Instagram for employee stories, workplace culture, achievements, and behind-the-scenes updates.
3. Recent News Articles
   Check the latest news to learn about product launches, leadership changes, market challenges, and company growth.
4. Employee Review Platforms
   Use platforms like Glassdoor to understand company culture, leadership, and employee experiences by identifying common review patterns.
5. LinkedIn Research
   Research your interviewers on LinkedIn to understand their background, interests, and career journey so you can build stronger conversations during the interview.

Strong research shows genuine interest, improves your confidence, and helps you stand out as a well-prepared candidate.

Create Your One-Page Briefing Sheet

Synthesise your research into a single-page document that you can review the night before and morning of the interview. Include: company mission, three recent developments (product launch, funding round, new market entry), top competitors, and two to three tailored questions you want to ask the panel. 

For example: “I noticed the company recently expanded into Southeast Asia. How is that shaping the priorities for this team?” or “Your LinkedIn shows you moved into this role from operations. What surprised you most about the transition?” These questions demonstrate genuine curiosity and research depth, not just generic interest.

Interview Preparation: Practice Questions Using STAR

Knowing your achievements is one thing. Presenting them clearly and compellingly under pressure is another. That is where structured practice comes in, and for behavioural interview questions, the STAR method is the gold standard. Behavioural questions are used in 65% of interviews, making this technique essential preparation.

Understanding the STAR Method

STAR stands for Situation, Task, Action, Result. It is a structured manner of responding to behaviour-based interview questions by discussing the specific situation, task, action, and result you are describing. The framework keeps your answers focused, evidence-based, and easy for the interviewer to follow.

Here is why it works: Behavioural interviewing exists to objectively measure a potential employee’s past behaviours as a predictor of future results. Employers believe that how you handled challenges, collaboration, or deadlines in the past is the best indicator of how you will perform in the role they are hiring for. Many organisations subscribe to the philosophy of “hire the person, teach the skills,” which places behavioural competencies front and centre.

The STAR method has been endorsed widely, from the Harvard Business Review to professional coaching bodies, precisely because it mirrors how hiring managers evaluate responses. Allocate roughly 20% of your answer to the Situation, 50% to the Action (the core where the interviewer assesses your actual capability), and 20% to the Result, ideally quantified.

Three Common Questions with STAR Examples

“Tell me about a time you overcame a challenge.”

Situation: Briefly set the scene (e.g., “During my final-year project, our team lost a key member two weeks before the deadline”).

Task: State your responsibility (e.g., “I needed to redistribute the workload and keep morale high”).

Action: Describe what you did (e.g., “I mapped out remaining tasks, took on the data analysis myself, and set up daily 15-minute check-ins to track progress”).

Result: Quantify the outcome (e.g., “We submitted on time and received a distinction, with the professor noting our resilience”).

“Describe a situation where you worked in a team.”

Follow the same structure, focusing on your specific role, how you facilitated collaboration, and the measurable impact your teamwork had on the project outcome.

“Give an example of when you showed leadership.”

Leadership does not require a formal title. Highlight initiative, influence, and results, whether you led a volunteer project, mentored a peer, or took charge during a crisis.

Mock Interview Practice Techniques

Knowledge of STAR is useless without rehearsal. Record yourself answering three to five common behavioural questions on your phone. Play it back and listen for filler words (“um,” “like”), pace, clarity, and whether your energy conveys confidence. Aim for 90-second answers, long enough to provide detail, short enough to hold attention. If you have access to a friend or mentor, run a mock interview and ask for honest feedback on body language and coherence.

If you are serious about refining your answers and want expert feedback, Leverage Edu’s career counsellors can run tailored mock interviews and help you structure your stories for maximum impact.

Plan Your Logistics: Date, Route & Tech Checks

Confidence collapses when logistics go wrong. Arriving flustered, late, or caught off guard by a tech failure undermines even the best preparation. Planning the practical details might feel mundane, but it is the foundation that lets you focus entirely on the conversation itself.

Confirm Details and Set Reminders

Double-check the interview date, time, and format. Is it in person, by phone, or by video? If in-person, confirm the exact address and building entrance. If virtual, test the meeting link. Save the interviewer’s contact details (phone and email) in case you need to reach them on the day. Set two calendar reminders: one 24 hours before to review your notes and one hour before to start final preparations.

Physical Interview Logistics

If the interview is in-person, plan your route the day before. Check distance, parking availability, and public transport schedules. Aim to arrive 10 to 15 minutes early, accounting for security or reception check-in time. Have a backup transport option in mind in case your primary plan fails. Running late triggers stress hormones that undermine your composure. Arriving early gives you time to use the restroom, take a few deep breaths, and enter the room calmly.

Virtual Interview Tech Setup

For video interviews, update your device software and test your camera, microphone, and internet connection at least 24 hours in advance. Position your camera at eye level (stack books under your laptop if necessary), ensure your face is well-lit (natural light from the front is ideal), and check that your background is tidy and professional. Mute notifications on your computer and phone. Log in to the meeting link 30 minutes early to troubleshoot any access issues. Have a backup device (phone or tablet) charged and ready in case your primary setup fails.

The 24-Hour Countdown Checklist

Day before: Review your company briefing sheet, CV-to-JD mapping, and STAR stories. Lay out your complete outfit, including shoes and accessories. Pack your interview kit (multiple CV copies, notebook, pen, ID, water bottle). Get to bed early.

Morning of the interview: Eat a light, balanced breakfast. Do a final tech test if virtual. If in-person, leave with a 30-minute buffer beyond your estimated travel time. Before entering the interview space (or logging in), take five slow, deep breaths to centre yourself.

Choose the Right Interview Attire

First impressions matter, and professional attire plays a major role in how recruiters perceive you. Research the company’s dress culture through social media, employee photos, and industry standards. When unsure, dress slightly more formally than the company’s usual style.

For corporate or formal settings, choose business attire such as a suit or blazer. For startups or creative roles, polished smart-casual clothing works well. Ensure your clothes are clean, ironed, and professional, with neat grooming and minimal accessories or fragrance.

For video interviews, dress professionally from head to toe, as it boosts confidence and helps prevent awkward situations if you need to stand during the call.

Prepare your complete outfit the night before to avoid last-minute stress on interview day.
