The Complete Job Interview Preparation Guide

Most interviews are lost before they begin — not because of poor performance in the room, but because of insufficient preparation beforehand. Interviewers can tell within the first few minutes whether a candidate has done their homework. The good news: thorough preparation is entirely within your control, and it makes a dramatic difference.

Research the Company and Role (Budget 2–3 Hours)

Generic research ("they make software") is not enough. You need to understand the company's current situation, challenges, and where this role fits in.

• Read the company's "About" page, mission, and recent news
• Check their LinkedIn page — recent posts, company size, growth
• Read Glassdoor reviews (pay attention to patterns, not outliers)
• Understand their main product or service — use it if possible
• Research your interviewer on LinkedIn — shared interests build rapport

The 5 Questions Every Interview Has

Regardless of industry or role, these questions appear in almost every interview. Prepare a strong answer for each:

• "Tell me about yourself" — a 90-second professional narrative, not your life story
• "Why do you want to work here?" — reference specific things you researched
• "What's your greatest weakness?" — choose a real one, explain what you're doing about it
• "What are you looking for in your next role?" — be specific: the type of work, growth, or impact you want, tied back to why this company fits
• "Do you have any questions for us?" — always have 3 prepared (more on this below)

The STAR Method for Behavioural Questions

"Tell me about a time when you..." questions require structured answers. The STAR method gives you a framework: Situation (what was the context?), Task (what were you responsible for?), Action (what specifically did you do?), Result (what was the measurable outcome?). The Result part is where most candidates fall short — always quantify if possible ("increased sales by 20%", "reduced churn by 15%").

Questions to Ask the Interviewer

The questions you ask reveal as much about you as the answers you give. Avoid questions about salary or benefits in a first interview. Instead:

• "What does success look like in this role after 90 days?"
• "What are the biggest challenges the team is facing right now?"
• "How would you describe the team culture?"
• "What do you enjoy most about working here?" (great for building rapport)

Online Interviews: What Changes

Most interviews today happen over Zoom, Google Meet, or Teams. The fundamentals are the same — but the logistics are completely different. A technical glitch or messy background can distract from an otherwise strong performance.

• Test your camera, microphone, and internet connection the day before — not 2 minutes before
• Use a neutral, well-lit background: natural light in front of you, not behind (no window behind you)
• Log in 5–10 minutes early to catch any last-minute issues
• Look at the camera when speaking, not at the interviewer's face on screen — it creates real eye contact
• Mute phone, close notifications, disable pop-ups on your computer
• Use it to your advantage: have the job description and your notes open in another tab
• If the connection drops — stay calm, reconnect, and briefly acknowledge it without over-apologising

The Day-Before Checklist

• Confirm time, location (or video link), and interviewer's name
• Print or have your CV ready on your phone
• Prepare your outfit — don't leave it to the morning
• Get a good night's sleep (genuinely more important than last-minute cramming)
• Plan to arrive 10 minutes early (or log in 5 minutes before for video)
