Interview etiquette is how you act and communicate to show that you are professional, respectful, and prepared. In the tech industry, your skills might get you the interview, but how you show up can make or break the offer.
1. Why Etiquette Actually Matters
Good etiquette is your secret power because it helps you build confidence and makes you look like a reliable, collaborative future teammate.
Good etiquette helps you:
Make a Killer First Impression: Showing up on time and looking sharp counts. Respect everyone’s time: interviewers notice when you’re organised.
Show Confidence Without Being Arrogant: Even if you're nervous, good etiquette conveys competence without arrogance.
Stand Out as a Collaborator: Companies want people who are not just smart but pleasant to work with.
Tip: Everyone gets nervous. Take a few slow breaths. Interviewers expect humans, not robots, and are understanding. It's perfectly fine to let them know if you need a second to reorient yourself or think about an answer.
2. The Basics
Response time: Aim to respond to interview invites/requests quickly, ideally within 2 business days.
This shows organisation and respect for the recruiter's time.
Homework: Check out the company and their values, the role, and the interviewers. The better your knowledge and understanding are, the more you’ll be able to engage confidently in the interview.
This shows genuine interest
Attire: Dress the part. In tech, smart casual is usually safe. Dressing well also puts you in the right professional mindset.
Communication: Listen actively, pause before answering, and explain your thoughts clearly.
This shows strong communication skills and collaboration potential
Tone: Be professional but human. polite and respectful, but don’t be afraid to show your personality.
This creates a great impression of confidence and approachability
3. Etiquette by Interview Format
Knowing what kind of interview you’re walking into makes a big difference to your preparation and your etiquette. The first thing you want to confirm is whether it’s online or in person, and if the company hasn’t said, it’s completely fine to ask.
Online interviews: Check your tech setup, background, lighting, audio and camera angles. Your body language and engagement on screen matter significantly.
In-person interviews: Punctuality is paramount. Focus on a confident handshake/introduction, posture, and eye contact.
Panel interviews: Balance addressing multiple interviewers, maintain eye contact with everyone, and manage questions without favouring just one person.
Technical interviews: Explain your thought process clearly and be structured in your approach to coding challenges or problem-solving.
Culture fit interviews: Show awareness of company values, team dynamics, and detail how you handle collaboration, conflict, and feedback
4. Talking About Your Experience & Asking Questions
Structured Storytelling
Use real examples that show what you did, the challenges you faced, and the results you achieved.
Tip: Keep answers structured and concise, using a framework like STAR (Situation, Task, Action, Result). Tailor your examples to the role to highlight relevant skills.
Asking Smart Questions
Asking thoughtful questions demonstrates curiosity, preparedness, and genuine interest, signalling respect for the interviewer’s time and insights.
Focus: Ask about the team, culture, tech stack, or how success is measured in the role.

Follow Up & Communication
How you communicate after an interview is just as important as your behaviour during it. Good post-interview communication reflects your professionalism and ability to build positive relationships.
Send a Thank You: Send a quick, personalised note to the interviewer showing appreciation for their time.
Show Enthusiasm: Reiterate your genuine interest in the role.
Follow Up Gently: Wait 2-3 days, then check in politely to stay on their radar if you haven't heard back.
5. Common Missteps To Avoid
Misstep to Avoid | Why It Matters (The Impact) |
Being Late | Punctuality shows you value the interviewer’s time and sets a professional tone. Lateness raises doubts about reliability. |
No-Showing to the Interview | Never fail to show up without prior notice. This is a severe breach of professional trust, burns bridges immediately, and guarantees you will not be considered for any future role at the company. If an emergency arises, always contact the company or Talent Advisor immediately to reschedule. |
Poor Setup (Online) | Technical issues are distracting and hinder your ability to clearly demonstrate your skills. |
Unprofessional Environment | Unless clearly stated as a phone call, do not use your mobile phone. Phone connections are unstable, camera angles are unprofessional, and it gives the strong impression that you lack a dedicated setup. This can affect how the interviewer views your reliability and prioritisation. Taking a call from your car or phone should be a last resort. If unavoidable, let the interviewer know beforehand. |
Interrupting | Failing to listen actively or interrupting creates the impression of impatience or difficulty working collaboratively. |
Criticising Past Employers | Focus on what you’ve learned rather than criticising past experiences. Negative comments raise concerns about how you handle conflict. |
Inappropriate Tone | Maintain a professional yet friendly tone. A tone that is too casual or informal early on can suggest you aren’t taking the role seriously. |
Smoking or Vaping During the Interview | Never smoke or vape during your interview. This is highly unprofessional, distracting, and shows a lack of consideration for the professional setting and the interviewer. Maintain a focused, respectful, and professional presence at all times. |
Failing to Own Errors | If you make a technical error, acknowledge it immediately, correct it, and explain how you caught it. This demonstrates crucial self-awareness and debugging ability. |
Swearing or Inappropriate Language | Never swear or use informal/vulgar language. It immediately breaks professionalism, demonstrates poor judgment, and raises serious concerns about your ability to communicate respectfully in a work environment. |
Eating, Chewing Gum, or Chewing Food | Never eat, chew gum, or chew food during the interview. This is unprofessional, distracting, and shows a lack of respect for the interviewer's time and the formal setting. It’s okay to have some water or coffee to sip on |
Not Communicating | If you realize you can’t hit a technical assessment deadline, communication is your best recovery tool. Ghosting suggests a lack of accountability; asking for more time suggests professional project management. |
