As online interviews become increasingly common in the post-pandemic world, many candidates – especially Gen Z – have grown accustomed to the convenience and flexibility of connecting with recruiters through a screen. However, this comfort often leads to carelessness in areas that seem minor but can significantly impact the outcome.
At Greyfinders Vietnam, a professional recruitment consultancy, we've seen talented candidates miss out on job opportunities for simple reasons – like poor lighting or a muted microphone. So, what are the five small but often underestimated details in an online interview? Let’s break them down.
1. Failing to check equipment and connection
One of the most common pitfalls in online interviews is technical failure. While issues like unstable internet may seem out of your control, to the interviewer, it reflects a lack of preparation.
What you should do:
• Test your camera, microphone, and headphones at least 15–30 minutes beforehand
• Use the most stable device available – preferably a laptop over a mobile phone
• Always have a backup plan: secondary internet connection, power bank, or extra device
• Don’t let “Sorry, I can’t hear you” or “Your screen froze” become your first impression.
2. Poor camera angle and lighting
A dimly lit room, awkward camera angle, or distracting background can easily give off an unprofessional vibe – no matter how well you answer the questions.
To enhance your visual presentation:
• Use natural light or a ring light to evenly illuminate your face
• Position the webcam at eye level; avoid low or side angles
• Tidy your surroundings; keep the background clean and distraction-free
• A polished setup shows that you take the opportunity seriously.
3. Dressing too casually
Online doesn’t mean informal. What you wear communicates your respect for the interview and helps you mentally step into a professional mode.
Wardrobe tips:
• Men: solid-colored button-up shirt, neatly styled hair
• Women: blouse or lightweight blazer, natural makeup
• Avoid overly bright patterns or overly casual attire
• Even within a single frame, your outfit speaks volumes.
4. Awkward or unnatural communication
Many candidates either stare at the screen, read from a script, or avoid eye contact with the camera – all of which can come off as robotic or disengaged.
To improve online communication:
• Look into the webcam while speaking to simulate eye contact
• Use natural facial expressions, nods, and smiles to show engagement
• Avoid interrupting; let conversations flow smoothly
• Prepare talking points, not full scripts
• Authentic, smooth communication builds rapport – even through a screen.
Lack of preparation
Some assume online interviews are “less formal,” so they skimp on researching the company, reviewing the job description, or preparing thoughtful questions. This often leads to passive and unremarkable interviews.
Take it seriously – just like an in-person interview:
• Research the company and understand its mission, products, and culture
• Study the job description and match it with your skills
• Prepare questions for the interviewer to show your genuine interest
• Be ready to discuss your career goals, past transitions, and personal strengths
• Solid preparation helps you stay confident and leave a memorable impression.
Key takeaway: Professionalism lies in the details
An online interview is not just about showing up on Zoom. It’s a chance to prove you’re serious – and the smallest things can make or break your impression. With a few mindful adjustments, you can stand out as polished, prepared, and proactive.
