Why Interview Etiquette Matters
First impressions count. A study from Forbes reports employers form opinions within the first seven seconds of an interview — and sometimes even sooner.
That gives you virtually no time, but there are things you can do.
Professionalism shows:
- You respect the company’s time and values
- You can represent the business well in client-facing or team roles
- You’re serious about the opportunity
While qualifications get you shortlisted, your demeanour during the interview often determines whether you land the offer.
Before the Interview: How to Prepare Professionally
Confirm Details in Advance
- Know the date, time, and who you’ll be speaking with.
- Verify the format — in-person, phone, or virtual.
- Check location details or ensure your video platform works properly.
Research the Company
Taking time to research the company shows you’re serious, prepared, and proactive — qualities every hiring manager wants in a candidate.
It also allows you to tailor your answers, ask smarter questions, and demonstrate genuine interest in the role.
Arriving clued up about the company is a great way to make an impression.
Here’s what you should focus on:
Company Website
Start with the official site — look at the About Us page, recent news or press releases, and their product or service offering.
Take note of the company’s mission statement, leadership team, and core values. If their site mentions a commitment to sustainability, innovation, or diversity, consider how your experience or mindset aligns with that.
Example:
If a company highlights sustainability, you could mention how you helped reduce waste in a previous role or initiated an eco-friendly policy.
LinkedIn Company Page
The company’s LinkedIn page often includes updates on hiring, business growth, and employee culture. Check:
- Who works there
- What recent content they’ve posted
- Company size and growth trends
Look up your interviewer, if known.
A quick glance at their background might help you find shared interests or understand their role better.
Glassdoor and Employee Reviews
While not always 100% reliable, employee reviews can give a good impression of company culture, interview questions, and what to expect in the hiring process.
Google News
Search the company name to see if they’ve been in the press recently — especially around funding rounds, product launches, leadership changes, or controversies.
Being informed lets you speak with confidence and show you’ve done more than skim the job ad.
Understanding a company’s mission and culture shows initiative. Learn about:
- Their latest projects or news
- Leadership team
- Workplace values
Many companies have news sections detailing their projects and successes.

Professional Conduct During the Interview
Your behaviour during the interview speaks volumes — often louder than your answers. The goal is to come across as competent, confident, and respectful.
Let’s break it down:
Arrive Early — But Not Too Early
For in-person interviews, aim to arrive around 10 minutes before your scheduled time.
Any earlier might make things awkward for the employer and put unnecessary pressure on reception staff.
Arriving late, even by a few minutes, gives a bad first impression — especially in industries that value punctuality (which is most of them).
For virtual interviews, join the call 5 minutes early so you can handle any last-minute tech issues and start calmly.
Essentially, It won’t take as long as seven seconds for the interviewer to form an opinion if you arrive late, out-of-breath and sweating due to not planning properly.
Dress Appropriately
- Corporate roles: Suit or business attire
- Creative roles: Smart-casual is usually fine
- Tech startups: Neat, clean, and slightly dressy is a safe bet
When in doubt, err on the side of being slightly overdressed.
Make a Strong First Impression
When you first meet your interviewer:
- Smile and maintain eye contact
- Give a firm (but not crushing) handshake if in person
- Thank them for taking the time to meet you
Use their name if you can — it builds rapport. Speak clearly, sit confidently, and be aware of your posture.
Example:
“Thanks for having me today, Rebecca. I’ve been looking forward to learning more about the team and the role.”
Respect the Interview Format
Whether it’s a panel, one-to-one, or back-to-back rounds, follow the lead of your interviewer(s).
Don’t try to dominate the conversation.
Listen actively, and wait for cues before responding. If someone interrupts or corrects you, stay composed and professional.
Keep It Professional — Even in Small Talk
You might be offered a coffee, asked about your weekend, or discuss something topical.
Keep responses friendly but safe — avoid overly personal stories, complaints, or controversial opinions.
Good example:
“I spent the weekend getting some fresh air and clearing my head — always helpful before a big interview.”
Virtual Interview Etiquette
As remote roles become more common, so do video interviews.
Professionalism matters just as much online as it does in person — and it can be trickier to get right.
Test Everything in Advance
- Check your camera, mic, and internet connection at least an hour before the interview.
- Do a practice call with a friend to test your setup.
- Make sure you have the meeting link, password, and interviewer’s name handy.
Nothing kills momentum like 10 minutes of “Can you hear me now?”
Choose the Right Environment
- Sit in a quiet, well-lit space with minimal background noise.
- Use a neutral backdrop — avoid messy rooms, clutter, or anything too personal.
- If you’re using a virtual background, make sure it doesn’t glitch or distract.
Lighting should come from the front, not behind you. A natural light source or desk lamp works well.
Dress the Part
Yes, it’s tempting to wear pyjama bottoms. Don’t.
Dress as you would for an in-person interview — it sets the tone for you and shows respect for the process.
Stick with solid colours that contrast nicely with your background and avoid loud patterns that can pixelate on camera.
Maintain Virtual Eye Contact
This means looking at the camera lens, not the screen, when you’re speaking.
It feels odd, but it helps simulate eye contact for the viewer. When listening, you can look at the screen.
Try to avoid staring at your own video thumbnail — it can be distracting.
Minimise Interruptions
- Silence your phone and notifications
- Close unnecessary tabs and apps
- Let others in your home or workspace know not to disturb you
If something unexpected happens (e.g., your dog barks), stay composed, apologise briefly, and move on.
Most interviewers understand life happens — it’s how you handle it that matters.

A brief, thoughtful follow-up message helps you stand out and reinforces your interest.
What to Include:
- A thank-you
- A key takeaway from the interview
- A reaffirmation of your enthusiasm
- Optional: clarification of a question you may not have answered well
Sample Email:
Subject: Thank You – [Your Name], [Position] Interview
Hi [Name],

What are the 5 C’s of interviewing?
The 5 C’s of interviewing refer to five key qualities that candidates should demonstrate to make a strong impression during a job interview: Competence, Confidence, Communication, Compatibility, and Commitment.
Competence shows you have the skills and experience to do the job effectively. Confidence reflects your self-belief and helps build trust with interviewers. Communication covers how clearly and professionally you express your ideas, both verbally and non-verbally.
Compatibility focuses on how well you fit with the company culture and team dynamic.
Commitment signals your interest in the role and the organisation long-term. Together, these five traits give employers a well-rounded view of you as a candidate and help them assess whether you’re the right fit for the job. Preparing examples that demonstrate each of the 5 C’s can help you stand out and make a lasting impression during the interview process.
How do you give a perfect interview answer every time?
To give a perfect interview answer every time, focus on structure, relevance, and delivery. Use the STAR method—Situation, Task, Action, Result—to keep your answers clear and concise.
Always tailor your response to the specific question, making sure it aligns with the job description and company values.
Avoid vague generalities; instead, provide specific examples that highlight your skills and achievements.
Keep your tone confident but not arrogant, and maintain eye contact if in person or on video.
Practice is crucial—rehearse common questions aloud so your answers feel natural, not scripted.
Listen carefully to the question, pause briefly if needed, and don’t rush.
Be honest; if you don’t know something, say so, but show a willingness to learn.
Finally, wrap up answers by linking back to how your skills or experience will benefit the employer, making it clear you’re a strong fit for the role.
How do you ace an interview every time?
To ace an interview every time, preparation is key. Research the company thoroughly—understand its mission, values, products, and recent news.
Study the job description and identify how your skills match what they’re looking for. Prepare answers to common interview questions using the STAR method, and rehearse them out loud.
Practice your body language, tone, and eye contact to convey confidence and professionalism.
Dress appropriately for the company culture, arrive on time, and bring any materials you might need.
During the interview, listen carefully, answer questions clearly and concisely, and show enthusiasm for the role.
Ask thoughtful questions that show you’ve done your homework.
Finally, follow up with a short thank-you email to reinforce your interest and professionalism.
Consistently applying these habits will make a strong, lasting impression and significantly boost your chances of success at every interview.
What are 5 tips for a successful job interview?
