1. Pre-interview preparation and the visual code
What you wear is a signal, not a superficiality. Interviewers read your clothing choices as evidence of how seriously you've researched the company, how well you understand professional norms, and how much you respect their time. Dress with intention — calibrated to the role, not to generic advice.Dress code by role type
Colors to avoid
Before choosing your outfit, look at the company's website, LinkedIn page, and any available photos of the team. Mirror the level up — dress one step above the typical employee, not two. Overdressing for a startup is as distracting as underdressing for a law firm.
2. The critical first 90 seconds
The window between walking through the door and sitting down is where many interviews are won or lost. Interviewers begin forming judgements the moment they see you — at the reception desk, in the hallway, or on a video call screen. Every element of those first 90 seconds can be engineered.Timing and arrival strategy
Common timing mistake: Arriving more than 20 minutes early can create awkwardness for the interviewer and signal poor time management. If you're very early, wait nearby — a café, your car, or a lobby — and enter at the 10-minute mark.
3. Small talk and the professional pitch
Small talk is not filler — it's a performance. The rapport you build in the first two minutes of casual conversation directly affects how the interviewer interprets your answers throughout the session. Prepare it as carefully as your STAR responses.The scripted opening
"Hi, I'm [Name], thank you for meeting me. I've been looking forward to discussing how my skills can contribute to [Company Goal]."
The Present-Past-Future pitch framework
When asked "Tell me about yourself," most candidates either ramble or deliver a rehearsed monologue that sounds hollow. The Present-Past-Future structure gives you a narrative arc that feels natural and lands with purpose.Start with your current role — this grounds the interviewer immediately. Summarise the most relevant past experience — not your full career history. End with why you're excited about this specific future opportunity. That last beat is what separates a memorable pitch from a CV recitation.
4. Body language and psychological mirroring
Non-verbal communication accounts for a significant portion of how confidence and trustworthiness are perceived. Two techniques — the Steeple and the Chameleon Effect — are consistently cited by behavioural researchers as high-impact, low-risk tools for projecting competence and creating rapport.The Steeple and Open Palms
The Steeple
Press your fingertips together in a steeple shape while speaking. This gesture is used by leaders and experts across cultures to signal authority and conviction. Use it when making a key point — not throughout the interview.
Open Palms
When listening or responding to sensitive questions, keep your palms visible and facing slightly upward. Open palms are universally read as an indicator of honesty and openness — the opposite of closed, crossed-arm postures.
Mirroring: the Chameleon Effect
How to mirror without being obvious
Wait one minute before reflecting. Immediately mirroring a movement looks deliberate. A 60-second delay makes the synchronisation feel natural and unconscious — which is when it has the most powerful effect on rapport.
Match energy, not actions. If the interviewer is measured and precise, slow your speech slightly and reduce hand gestures. If they're expressive and fast-paced, meet their energy. This is less about copying specific movements and more about calibrating your register to theirs.
Echo tone and vocabulary. If the interviewer uses technical language, mirror it back. If they use casual phrasing, don't respond with overly formal speech. The goal is to appear as a natural cultural fit — someone who already speaks the company's language.
What to avoid: Do not fold your arms, slouch, or display nervous tics — leg bouncing, hair touching, pen clicking. These signal anxiety and undermine the impression of calm competence you've built through your preparation.
5. Virtual interview mastery
Virtual interviews introduce a unique layer of technical variables that can undermine your preparation if ignored. Most candidates focus entirely on their answers and neglect the environment and setup — which the interviewer is evaluating from the first second on screen.Eye contact with the lens
Look directly into the camera lens — not at the person's face on screen. This simulates true eye contact. Place a small sticker or arrow next to your camera as a reminder.
Technical setup optimisation
Camera at eye level. Light source in front of you, not behind. Use a professional screen name. Test your audio at least 30 minutes before the call. Close all notifications.
Engagement in a digital space
Use active listening cues: nod deliberately, lean slightly forward, maintain a neutral and engaged background. The camera compresses your energy — project slightly more than you would in person.
Before the call
Test camera, microphone, and lighting. Close all background apps and browser tabs. Have a glass of water and your notes off-screen.
During the call
Look at the lens when speaking, the screen when listening. Pause before answering — the lag forgives it and signals thoughtfulness.
Background & appearance
Use a clean, neutral, professional background. Dress fully — including below the waist — in case you need to stand.
Technical contingency
Have the interviewer's phone number saved. If the call drops, rejoin immediately. A one-line message — "Rejoining now" — removes anxiety for both parties.
6. The "no-do" list and follow-up
What you don't do in an interview is as important as what you do. Certain physical behaviours and communication patterns consistently lower perceived competence — regardless of the quality of your answers.Physical and communication don'ts
- ✗ Fold your arms, slouch, or display nervous tics — these signal anxiety and closed-off energy
- ✗ Badmouth a previous employer — even if prompted, reframe negatives as learning experiences
- ✗ Ramble or speak in monotone — vary your pace and pitch; silence is better than filler words
- ✗ Avoid nervous habits: touching your face, clicking a pen, bouncing your leg, or checking your phone
- ✗ Answer a question you weren't asked — listen precisely and respond to what was actually asked
The personalised thank-you email
Send a personalised thank-you email within two hours of the interview. Reference one specific detail from the conversation — a project they mentioned, a challenge they described, a question that surprised you. This specificity proves you were genuinely present and converts a courteous gesture into a memorable impression.
- ✓ Send within 2 hours — while the conversation is still fresh for both parties
- ✓ Reference a specific detail from the interview to prove attentiveness
- ✓ Reiterate your enthusiasm for the role in one sentence — direct and unambiguous
- ✓ Keep it to 4–6 sentences — brevity signals respect for their time
