Most interviews are won or lost in the preparation. Here's everything you need to walk in confident, answer well, and leave a strong impression.
Practise Your Interview with AI →Job interviews are predictable in ways most candidates don't take advantage of. The questions follow patterns. The assessment criteria are consistent. The mistakes candidates make are almost always the same ones. What separates the people who get offers from those who don't isn't raw ability or luck — it's preparation quality. This guide covers what to do before, during, and after your interview so you walk in with a genuine edge over the other candidates in the room.
Read their website, recent news, and LinkedIn. Know their products, competitors, and any recent developments. Interviewers notice immediately when candidates haven't done this.
Go through the job description line by line and identify which parts of your background are most relevant. These become your key talking points throughout the interview.
Write out five or six specific examples from your career covering leadership, problem-solving, conflict, failure, and initiative. These cover the vast majority of behavioural questions.
Thinking through answers and delivering them are completely different. Practise speaking your answers aloud — ideally timed, ideally recorded — at least once before the real thing.
Prepare at least three thoughtful questions for the interviewer. Questions about the team's challenges, how success is measured, or the company's strategic priorities signal genuine engagement.
Confirm the format, location or link, who you're meeting, and expected duration. Arriving prepared for the right format removes avoidable stress on the day.
This question opens almost every interview and most candidates underperform on it. Use the Present–Past–Future structure: where you are now, the most relevant experience from your background, and why this role is the right next step. Keep it to 60–90 seconds. A strong opener sets a confident tone for everything that follows.
Situation, Task, Action, Result. Every "tell me about a time when..." question should follow this structure. The most common mistake is spending too long on the situation and not enough on the action and result — interviewers care most about what you specifically did and what the measurable outcome was. Aim for one concrete number per example.
Mentioning something specific — a recent product launch, a news story, a challenge in their market — signals genuine preparation that generic candidates don't demonstrate. Even one or two specific references changes how an interviewer perceives your level of interest. This is particularly effective when answering "why do you want to work here?"
Unless asked for detail, most answers should be between 60 and 90 seconds. Interviewers who are losing interest will rarely tell you — they'll just form a negative impression. If you're not sure whether to go longer, you can ask: "Would you like me to go into more detail on that?" This shows self-awareness and gives them control.
A brief pause before a thoughtful answer is far better than a rushed, unfocused one. Say "that's a good question, let me think about that" if you need a moment — this signals composure rather than uncertainty. The instinct to fill silence immediately leads to the rambling answers that interviewers find hardest to assess positively.
"What's your biggest weakness?" is a test of self-awareness, not an invitation to confess. Pick a genuine, relevant weakness, be honest about it, and then describe concrete steps you've taken to address it. Candidates who either claim to have no weaknesses or give transparent non-answers ("I work too hard") are immediately less credible than those who answer honestly.
Reading the room matters. A formal, structured interviewer wants precise, professional answers. A more conversational interviewer responds better to warmth and narrative. The consistent thread is enthusiasm — a candidate who appears genuinely interested in the role is more memorable than one who delivers technically correct answers with no energy.
"What's the biggest challenge the team is facing right now?" and "How will success be measured in this role in the first six months?" are far stronger than "how many days holiday do I get?" The questions you ask signal how you think. Candidates who ask about challenges and outcomes come across as mature, commercially aware, and genuinely motivated.
Regardless of what happened, criticising a former manager or company makes you look difficult and indiscreet. Interviewers know they may one day be on the receiving end of the same treatment. If asked why you're leaving, focus on what you're moving toward — growth, new challenges, specific opportunities — rather than what you're moving away from.
A brief, specific thank-you email after the interview is a low-effort step the majority of candidates skip. Keep it to three or four sentences — thank them for their time, reference one specific thing from the conversation, and reaffirm your interest. It won't rescue a poor interview, but it consistently reinforces a good one and keeps you front of mind during the decision.

Research the company thoroughly — their products, recent news, competitors, and culture. Re-read the job description and map your experience to each requirement. Prepare specific examples using the STAR framework for behavioural questions. Practise your answers out loud, not just in your head. Prepare at least three thoughtful questions to ask the interviewer. And confirm the practical logistics — location, format, who you're meeting, and how long it will last.
Use the STAR framework: Situation (set the context), Task (what you were responsible for), Action (what you specifically did), Result (what the outcome was, ideally with a number or measurable impact). Keep each example to around 90 seconds. The most common mistake is spending too long on the situation and not enough on the action and result — interviewers care most about what you did and what happened because of it.
Research the company's culture before deciding. For corporate, finance, or legal roles, smart formal is usually expected. For tech or creative companies, smart casual is typically appropriate. When in doubt, dress one level above what you expect the office dress code to be — it's always better to be slightly overdressed than underdressed for a first impression.
Aim to arrive at the building 10 to 15 minutes early, but don't enter reception more than 5 to 10 minutes before your scheduled time. Arriving too early can create awkwardness for the interviewer and suggest poor time management. If you're running late for any reason, call ahead as soon as you know — most interviewers are understanding if you communicate proactively.
Don't bluff. It's far better to say "I don't have direct experience with that, but here's how I'd approach it" or "I haven't encountered that specific situation, but a similar challenge I've faced was..." Interviewers respect honesty and problem-solving instinct far more than a fabricated answer. If the question is knowledge-based rather than experience-based, it's acceptable to say you'd need to research it further and explain how you'd go about doing so.
